Migration to a new server with a new php version

[Nicoolas]

Hello Team,

I had to move my forum and website from an old server to a new server, this new server has php8.0. When I try to reach the admin pages, just after login, the following error appears :

Fatal error: Cannot use "parent" when current class scope has no parent in /var/www/xxxxxxxxxxx/public/system/Theme/Theme.php(2632) : eval()'d code on line 27

I tested with php8.1 and now back to php8.0

Thanks for your help.

Best regards,

Nicoolas

Note : I used the ips4 and all extensions are installed, but the problem remains.

Use the RECOVERY MODE to access the Admin CP and disable 3rd-party resources. One of them is outdated.

Thanks @Adriano Faria, I was able to regain access to my Admin CP, now, it's time to check what cause this issue.

Note, you also cannot use PHP 8.1 at present, as we have not yet updated for that version. 8.0 would be the highest

Thanks for your input @Marc Stridgen, I revert back to php 8.0 and applied the following action :
