Extension Manager

Peter van Westen ADMIN

Did you update all extensions to the latest versions before upgrading Joomla to 4?
Also, why are you going for Joomla 4 and not 5?

Try deleting these folders:

/plugins/system/regularlabs
/libraries/regularlabs

(You will get other errors now).

Then reinstall the Regular Labs extensions…

Yes, I updated all extensions to their latest versions before updating to J4. I have always thought going to J4 first then J5 was the best way to go rather than J3 directly to J5. Is this not the case?

I was going to delete the folders you mentioned but first I tried uninstalling all Regular Labs extensions via the Joomla extension manager, and I got this:

The PLG_ACTIONLOG_REGULARLABSMANAGER extension is part of a package which does not allow individual extensions to be uninstalled.
The PLG_CONSOLE_CACHECLEANER extension is part of a package which does not allow individual extensions to be uninstalled.

I then deleted the folders you mentioned and tried uninstalling again and got the same messages as above.

Since I had no success with uninstalling, that I tried updating the existing installs and got this:

Attempted to load class "CacheCleaner" from namespace "RegularLabs\Module\CacheCleaner\Administrator\Helper".
Did you forget a "use" statement for another namespace?

Symfony\Component\ErrorHandler\Error\
ClassNotFoundError

Error
Class "RegularLabs\Plugin\System\CacheCleaner\Cache" not found

I saved the stack traces for both of the above and can post them if they're helpful. I should also add that a search of the extensions table in the database via PHPMyAdmin comes up with zero results for 'regular'.

What a mess. Sorry but I'm really stuck here! Now the admin is broken and throws the last errors shown above.

Can you give me (super) admin and (s)ftp access so I can take a look?

I uninstalled the Regular Labs packages you still had installed, deleted this file:

/administrator/cache/autoload_psr4.php

And reinstalled the Regular Labs Extension Manager. And all seemed fine.

But after installing Cache Cleaner or ReReplacer (or anything else), new errors come up, until I delete that autoload_psr4.php file again.
It looks like Joomla is not able to update that file, causing the issues you have. Maybe a file/folder permissions issue.
But this is outside the control of my extensions. This is an issue on your server/setup.

OK, thanks for doing that. I will find a solution to the cache file issue and see if that doesn't fix things.

The issue is caused by you having the "Namespace Updater" plugin disabled.

Funny I just found the same issue here: forum.joomla.org/viewtopic.php?t=1005841

However when I try to enable it, it shows as locked and fails with the error "Edit state is not permitted." Any idea on that? Looking through the extensions table in PHPMyAdmin I don't even see that plugin listed.

No idea. Best to ask around on the Joomla forum.
