    So, I followed this guide on upgrading debian 10 first, then this guide on upgrading ISPConfig.
    But when i try starting the apache service i get the following error.
    ● apache2.service - The Apache HTTP Server
         Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
         Active: failed (Result: exit-code) since Wed 2022-08-17 21:48:04 UTC; 33s ago

    What am I supposed to do with that php7.3 file that's not loading? Am I supposed to remove it, because the line in the apache2.conf just seems grab any file with that *.load. There's also a php7.3.conf file in the mods-enabled folder, should i remove that as well?

    Edit: Just so a possible solution elsewhere is to disable php.7.3 module with a2dismod and enable the current version of php instead. Is this the way to do it instead of deleting the php7.3 files?

    Yes, you can not just delete mod_php for PHP 7.3 without disabling it.

    Much appreciated. Just wanted to make sure about the solution I found as I didn't want to do anything that could potentially result in more downtime for my server.
