Solved Class "Kunena\Forum\Plugin\Kunena\Easysocial\Extension\Easysocial" not found

I have the same problem, and I have tried what you suggested but I'm still going round in circles. Entering the Kunena dashboard produced the error message: Class "Kunena\Forum\Plugin\Kunena\Easysocial\Extension\Easysocial" not found

Workaround: I have restored a backup and am once again using the un-supported version 6.4.9 of Kunena on my Joomla 6.0.3 site, which is working perfectly for me. Hopefully a future version will solve the issue, and then I will upgrade version 7.x

Do you have any suggestions, please? Thank you.

Hallo,
mein Problem konnte nicht gelöst werden. Aber da ich sowieso einen großen Berg an Altlasten in meinem Joomla Sytem hatte, habe ich mich entschlossen, es neu aufzusetzen. Und siehe da, Kunena praktisch neu installiert und keine Fehlermeldung mehr. Ich weiß nicht, wie man Daten aus einer vorhandenen Installation von kunena migriert, aber ich denke generell würde es funktionieren wenn man kunena komplett deinstalliert und dann neu installiert. Natürlich ohne Garantie. Bitte schreiben Sie mir, wenn es funktioniert hat. Grüße, Harry

Hello,

I hadn't a test site with easysocial and Joomla! 6.0, i had only a test site with easysocial and Joomla! 5.3.x, it has make me some headeache because of easysocial to update this test site to Joomla! 6.0.

Try to delete the following file : \joomla\administrator\cache\autoload_psr4.php; then when you reload the page Joomla! will recreate it automatically


 

UPDATE 24 Feb 2026
I originally tried to upgrade Kunena to 7.0.1 on my Joomla 6.0.3 site and got the "Class "Kunena\Forum\Plugin\Kunena\Easysocial\Extension\Easysocial" not found" error. I don't use EasySocial on my site and the Kunena - EasySocial Integration plugin is disabled. Why does this error message happen?

Today I tried upgrading version 6.4.9 of Kunena on my Joomla 6.0.3 test site to 7.0.1 again, but this time the installation completely failed. After the failure I did not try and install pkg_kunena_languages_v7.0.1
I then uninstalled version 6.4.9 but the complete site stopped working, so I had to restore the database and files for a second time.

I believe I have met all the requirements for Kunena 7.0, except perhaps the following installed modules may have been developed for previous versions of Kunena? What should I do?
Kunena Statistics 6.2.0
Kunena Search 6.2.0
Kunena Latest 6.2.0

Lastly, my database is MySQLi 11.4.10-MariaDB, however the requirement is MySQL: version 8.4.0 or greater. Is this OK?

Thank you,

Andy

Hello,

You can try please to enable debug mode into Joomla! and Kunena configuration panel and too set error report to maximum in Joomla! configuration panel to see what is loading this easysocial plugin

Did-you had tried to delete the following file to see if it does something : \joomla\administrator\cache\autoload_psr4.php ?

Your mariaDB version is ok

You can try this change if it fix the issue : github.com/Kunena/Kunena-Forum/pull/10004
