Hello Mahmut Manav,

Sorry for the inconvenience you're experiencing. We've identified the root cause of the issue with the page layouts and pre-made blocks, thanks to valuable assistance from one of our users. A permanent fix will be included in the upcoming update.

In the meantime, please apply this temporary solution:

Open the file: /components/com_sppagebuilder/helpers/ajax.php

Then, add the following line at line 22:

use Joomla\Filesystem\File;

This should resolve the issue. If this doesn't solve the issue, please reach out and I'll look into it more deeply.

Hope this helps!

Best regards

Hello Mahmut Manav, This hasn't worked for me. I still cannot access layout bundles.
