Hi,

I updated my website to Joomla4 and installed the extensionmanager again after clearing the cache.

But I get this error: Class "RegularLabs\Library\Parameters" not found

Please advise me what to do.

Hi Peter,

These folders are not present!

Hi, here the info you asked for.

Note:

I did have a similar issue witht the following error message both in the front-end and in the back-end (I don't know which of the updates of yesterday/today did cause that):

Going to the Extension Manager I was also having this:

I did uninstall the Extension Manager and reinstalled it... and it seems to be OK now.

Thanks for solving this problem.
Although it's strange that I did the same steps and it didn't work.

We experienced the same error. Removing the 2 directories Peter noted and then reinstalling the extension manager resolved the issue for us.

We're upgrading a different site today and when we received the error message this time the steps described above didn't resolve the error. I removed the RL folders located in Libraries and Plugins and also reinstalled the extension manager and cleared caches, but the error message persists.

Update: Uninstalling the RL extension manager package as well as the RL Library package, and then reinstalling the extension manager fixed it in this case. I had previously also removed the RL folders in the libraries and the plugins/system folders, too.

After going around this circle a few times I uninstalled Extension Manager yet again. The two folders mentioned above were already deleted. I also uninstalled the Regular Labs -Library (Package) and Regular Labs Library (Library). Then I reinstalled the Extension Manager again and everything was OK. I think it took me four tries to get there, but this worked.

I'm having this same issue. I uninstalled the package and made sure the library and plugin were deleted. I reinstalled the latest version (8.3.0) for Joomla 4 but am still getting:

Class "RegularLabs\Library\Parameters" not found.

When I check the files there is not ../libraries/regularlabs folder

Please try again


I deleted those folders and have tried to reinstall but it is still giving me that error.

I get a successful response when installing the extension

The Regular Labs Extension Manager v8.3.0 has been successfully reinstalled
info
The Regular Labs Extension Manager v8.3.0 has been successfully reinstalled
Latest changes:
v8.3.0 [23-May-2023]

+ Adds link to the documentation in the footer text
^ J4 Improves memory usage preventing memory exhaustion in some cases

I checked the extensions table and made sure there were no legacy entries.

The only place I can find reference to this is in administrator > components > com_refularlabsmanager > tmpl > main > default.php
Lines 15-18
use RegularLabs\Library\Document as RL_Document;
use RegularLabs\Library\DownloadKey as RL_DownloadKey;
use RegularLabs\Library\Parameters as RL_Parameters;
use RegularLabs\Library\Version as RL_Version;

Not sure if I'm helping or being confusing! I'm still getting the error and cannot manage all of my other RL extensions 🙁

Also, I'm assuming that I will need to reinstall all of my other Regular labs extensions...but will I have to update assignments on all of the modules (please say I won't have to)?

Works. I was able to update all other RegularLabs extensions.

thank you!
