Plugin Reference Cleaner
Author: Marcus Quinn Author URI: https://www.wpallstars.com Version: 1.2.4 License: GPL-2.0+
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:
"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.
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.
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.
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.
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.
