I tried to upgrade SP PB 3.8.10 to SP PB 5.2.3. But after doing this, the startpage shows the following error message:
"You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ') ORDER BY lft ASC' at line 3"
Trying to call the startpage "startseite" from backend-editor to frontend-editor, it shows the following error message:
"Sorry, there was a problem we could not recover from.
The server returned a "500 - Whoops, looks like something went wrong.""
But: If I try to edit any other page with the frontend-editor, there is no problem and it seems to work fine. so the problem seems to happen only with the startpage.
My next step: I downgraded back to SP PB 3.8.10, and there was no problem any more. Trying again to install SP PB 5.2.3, the problem with the startpage comes back. So finally I had to downgrade again.
I run Joomla 4.4.1, the PHP-Version is 8.1.26.
The database version is: 10.5.19-MariaDB-1:10.5.19+maria~deb10-log
How can I solve the problem and install the purchased SP PB 5.2.3?
Thank you for your help.
