Time to switch to using Joomla! 5.x
Joomla! 5.x was launched in October 2023 and yet still many many Joomlers are using the old Joomla! 3.10 or Joomla! 4.x CMS.
Joomla! 5 Compatibility Plugin
The Compatibility Plugin is enabled by default in the Joomla! 5 CMS.
Purpose: to enable Third Party Extensions which are not yet compatible with the Joomla! 5 CMS to continue to function after you update your website.
Its use will however adversely impact your website's performance in browsers.
Your website's page load times will be slower.
For this reason you may wish to avoid using extensions which require use of the Compatibility Plugin.
If all your website's Third Party Extensions are compatible with Joomla! 5 then you may disable the plugin.
The Joomla! Project has published a useful guide at the following link.

Is your website still using Joomla! 4?
The Joomla! Project recommend you try updating a backup of your live website before attempting to update your live website to Joomla! 5.
First check the PHP and MySQL used by your website's server are compatible with running Joomla! 5.
