+Easily remove references to deleted plugins that cause "Plugin file does not exist" errors in your WordPress admin.
 
 ## Description
 
-Have you ever deleted a plugin some other way than through the /wp-admin/plugins.php page? If so, you've probably been stuck with this annoying notification that can't be cleared:
+Have you ever deleted a plugin directly from the server or database and then been stuck with annoying error notifications that can't be cleared?
 
 "The plugin folder-name/file-name.php has been deactivated due to an error: Plugin file does not exist."
 
-This small WordPress utility plugin adds a "Remove Reference" button to these plugin deactivation error notices, allowing you to clean up the invalid plugin entries in the database.
+This small utility plugin adds missing plugins to your WordPress plugins list and provides a "Remove Reference" link, allowing you to safely clean up invalid plugin entries with one click.
 
-When WordPress detects a plugin file that no longer exists but is still referenced in the database as active, it displays an error notice. This plugin enhances those notices with a button that allows you to safely remove the invalid reference with a single click.
+### Key Features
 
-You can find these with `SELECT * FROM wp_options WHERE option_name = 'active_plugins';` — but the cleanup involves removing the rogue entry, and renumbering all others. This plugin can simply do that for you at the click of a button added to that WP standard notification.
+* Adds missing plugins directly to your plugins list
+* Provides a simple "Remove Reference" action link
+* Works with both single site and multisite WordPress installations
+* Includes helpful notifications explaining how to fix plugin errors
+* One-click auto-scroll to find missing plugins in large sites
+* Clean, user-friendly interface following WordPress design patterns
 
-It's probably something that should be added to WP core. If anyone from the core team wants to adopt this solution, it's GPL, so feel free.
+### How It Works
 
-Note: This plugin only needs to be installed and active if you have an error notification showing at /wp-admin/plugins.php, like this:
+When WordPress detects a plugin file that no longer exists but is still referenced in the database as active, it displays an error notice. This plugin:
-"The plugin folder-name/file-name.php has been deactivated due to an error: Plugin file does not exist."
 
-If you don't have this notification perpetually showing on your /wp-admin/plugins.php page, then you don't need this, but you might like to save or bookmark it for if ever you do.
+1. Detects all missing plugin references in your database
+2. Adds them to your plugins list with "(File Missing)" indicators
+3. Provides a "Remove Reference" link to safely remove them
+4. Shows clear notifications guiding you through the cleanup process
 
-## Features
+### Use Cases
 
-* Adds a "Remove Reference" button to plugin error notices
+* You've accidentally deleted a plugin via FTP
-* Works for both single site and multisite WordPress installations
+* A plugin was removed by another admin but references remain
-* Confirms before removing any plugin references
+* You've migrated from another site and have leftover plugin references
-* Simple, lightweight solution with no settings page required
+* Your hosting provider removed a plugin but didn't clean the database
-* Secure implementation with proper permissions checking
-* Compatible with WordPress 5.0+
 
 ## Installation
 
-1. Upload the plugin-reference-cleaner.php file to your /wp-content/plugins/ directory
+### From WordPress.org:
-2. Activate the plugin through the 'Plugins' menu in WordPress
+
-3. No configuration needed - the plugin works automatically
+1. Visit Plugins > Add New in your WordPress admin
+2. Search for "Fix 'Plugin file does not exist.' Notices"
+3. Click "Install Now" and then "Activate"
+
+### Manual Installation:
+
+1. Download the plugin ZIP file
+2. Go to Plugins > Add New > Upload Plugin
+3. Upload the ZIP file
+4. Activate the plugin
 
 ## Usage
 
-1. Navigate to Plugins > Installed Plugins
+1. After activation, navigate to Plugins > Installed Plugins
-2. If any "Plugin file does not exist" error notices appear, a "Remove Reference" button will be displayed
+2. If you have missing plugin errors, you'll see them in your plugins list with "(File Missing)" markers
-3. Click the button and confirm to remove the invalid plugin reference
+3. Click the "Remove Reference" link next to any missing plugin
-4. The page will refresh with the error notice removed
+4. The reference will be removed, and the error notification will disappear
+
+## Frequently Asked Questions
+
+### Is it safe to remove plugin references?
+
+Yes, this plugin only removes entries from the WordPress active_plugins option, which is safe to modify when a plugin no longer exists. It doesn't modify any other database tables or settings.
+
+### What happens after I remove a reference?
+
+The plugin entry will be removed from your active plugins list, and the corresponding error notification will no longer appear after you refresh the page.
+
+### Can I use this plugin on a multisite installation?
+
+Yes, the plugin works on both single sites and multisite installations. It properly handles network-activated plugins as well.
+
+### How do I know which plugin references should be removed?
+
+The plugin will only show "Remove Reference" links for plugins that are listed in your database but don't actually exist in your plugins directory. These are safe to remove.
+
+### Will this break my site?
+
+No. Since the plugin is only removing references to plugins that no longer exist, removing these references won't affect your site's functionality. In fact, it's cleaning up remnants that might be causing issues.
+
+### What if I accidentally remove a reference I shouldn't have?
+
+If you remove a reference to a plugin that you later want to reinstall, simply install the plugin again and activate it normally.
+
+### Do I need to keep this plugin installed and active after notices are cleared?
+
+Although this plugin consumes minimal disk space, and doesn't run unless you are on the /wp-admin/plugins.php page, you don't need to keep it active or installed if you don't have this notice to clear — but it is safe to, if you just want it as a part of your overall WordPress stack of enhancements and conveniences.
+
+## Screenshots
+
+1. Error message with explanation notification
+2. Missing plugin shown in the plugins list with "Remove Reference" link
+3. Auto-scroll feature that highlights the missing plugin

+5. Submit a pull request
+
+### Technical Details
+
+The plugin works by:
+1. Filtering the `all_plugins` array to add missing plugins
+2. Adding a custom "Remove Reference" action link via `plugin_action_links`
+3. Adding helpful notifications near error messages
+4. Providing a secure method to remove plugin references from the database

+Easily remove references to deleted plugins that cause "Plugin file does not exist" errors in your WordPress admin.
 
 == Description ==
 
-Have you ever deleted a plugin some other way than through the /wp-admin/plugins.php page? If so, you've probably been stuck with this annoying notification that can't be cleared:
+Have you ever deleted a plugin directly from the server or database and then been stuck with annoying error notifications that can't be cleared?
 
 "The plugin folder-name/file-name.php has been deactivated due to an error: Plugin file does not exist."
 
-This small WordPress utility plugin adds a "Remove Reference" button to these plugin deactivation error notices, allowing you to clean up the invalid plugin entries in the database.
+This small utility plugin adds missing plugins to your WordPress plugins list and provides a "Remove Reference" link, allowing you to safely clean up invalid plugin entries with one click.
 
-When WordPress detects a plugin file that no longer exists but is still referenced in the database as active, it displays an error notice. This plugin enhances those notices with a button that allows you to safely remove the invalid reference with a single click.
+= Key Features =
 
-You can find these with `SELECT * FROM wp_options WHERE option_name = 'active_plugins';` — but the cleanup involves removing the rogue entry, and renumbering all others. This plugin can simply do that for you at the click of a button added to that WP standard notification.
+* Adds missing plugins directly to your plugins list
+* Provides a simple "Remove Reference" action link
+* Works with both single site and multisite WordPress installations
+* Includes helpful notifications explaining how to fix plugin errors
+* One-click auto-scroll to find missing plugins in large sites
+* Clean, user-friendly interface following WordPress design patterns
 
-It's probably something that should be added to WP core. If anyone from the core team wants to adopt this solution, it's GPL, so feel free.
+= How It Works =
 
-Note: This plugin only needs to be installed and active if you have an error notification showing at /wp-admin/plugins.php, like this:

-"The plugin folder-name/file-name.php has been deactivated due to an error: Plugin file does not exist."
 
-If you don't have this notification perpetually showing on your /wp-admin/plugins.php page, then you don't need this, but you might like to save or bookmark it for if ever you do.

-== Usage ==
+== Frequently Asked Questions ==
 
-1. Navigate to Plugins > Installed Plugins
+= Is it safe to remove plugin references? =
-2. If any "Plugin file does not exist" error notices appear, a "Remove Reference" button will be displayed
+
-3. Click the button and confirm to remove the invalid plugin reference
+Yes, this plugin only removes entries from the WordPress active_plugins option, which is safe to modify when a plugin no longer exists. It doesn't modify any other database tables or settings.
-4. The page will refresh with the error notice removed
+
+= What happens after I remove a reference? =
+
+The plugin entry will be removed from your active plugins list, and the corresponding error notification will no longer appear after you refresh the page.
+
+= Can I use this plugin on a multisite installation? =
+
+Yes, the plugin works on both single sites and multisite installations. It properly handles network-activated plugins as well.
+
+= How do I know which plugin references should be removed? =
+
+The plugin will only show "Remove Reference" links for plugins that are listed in your database but don't actually exist in your plugins directory. These are safe to remove.
+
+= Will this break my site? =
+
+No. Since the plugin is only removing references to plugins that no longer exist, removing these references won't affect your site's functionality. In fact, it's cleaning up remnants that might be causing issues.
+
+= What if I accidentally remove a reference I shouldn't have? =
+
+If you remove a reference to a plugin that you later want to reinstall, simply install the plugin again and activate it normally.
+
+= Do I need to keep this plugin installed and active after notices are cleared? =
+
+Although this plugin consumes minimal disk space, and doesn't run unless you are on the /wp-admin/plugins.php page, you don't need to keep it active or installed if you don't have this notice to clear — but it is safe to, if you just want it as a part of your overall WordPress stack of enhancements and conveniences.
