Various plugin errors after update to 4.4.4

[kost36]

Dear people,
After update from 4.3 to 4.4.4 I am faced on various errors reading plugins mainly on path Joomla\Plugin\System\
As it seems jomla 4.4.4 is unable to execute various plugins like skipto or jooa11y or updatenotifications etc.
Is there any solution about this?
Thank's

Can you post the specific errors (turn debug/php error reporting on)?

Update Notifications - do you mean this one: https://extensions.joomla.org/extension ... fications/ (hasn't been updated in 9 years, for J3 only).

I think jooa11y is the default Accessibility checker plugin included in the Joomla core (so it should work). - https://joomla-projects.github.io/joomla-a11y-checker/ ( ).

I can't find any information on "skipto".

I can't find any information on "skipto".

Search for 'skip-to'. This plugin is part of Joomla 4+ core.

System - Skip-To Navigation
system / skipto
The plugin creates a dropdown menu consisting of the links to the important places on a given web page. This makes it easier for keyboard and screen reader users to quickly jump to the desired location by choosing it from the list of options.

Dear all,
sorry for the late reply but medical reasons kept me away from home. Unfortunately, with my allowance, I cannot try any of your suggestions because now it's impossible to get into administration page as well. I have already opened another ticket describing the error message I am facing to.
