Class 'JRequest' not found in Email Activation user plugin Topic is solved

[antonios]

Hi,
I just upgraded my site from J3.10.12 to J4.4.9
Initially everything seemed to go very smoothly. I could move back and forth within the back-end without problems
and the front-end seems to be working well, although with the new cassiopea template, the layout needs rearranging, but that's for later.
I updated a few components/plugins to the new J4 version. The updates seemed to have worked fine
however after a few minutes (after pushing on some link I reckon) the

An error has occurred.

0 Class 'JRequest' not found

message appeared, and to be honest don't really know what to do in order to restore the back-end functionality.
The front-end continues to work well apparently.

What updates did a do? .... Akeeba, the Spanish Language Package, PhocaGallery, ..maybe a couple of others which now can't remember....
Any help appreciated

Enable debug. Post stack trace.

I enabled debug in configuration.php by changing

Code: Select all

debug = 0 to debug = 1

The following info is shown:

The third party user plugin 'Email Activation' caused the error because it does not support Joomla 4. It needs to be disabled and then uninstalled or, alternatively, updated and re-enabled. No idea which extension it is or if it can be found from JED.

Use phpMyAdmin from the cPanel provided by your host to edit the database table _extensions. Locate the row with this user plugin and change the column 'enabled' from 1 to 0.

Thanks you @toivo & @Skarkykz!
I managed to re-enable the back-end!
