    I'm getting a 500 error on the ISPConfig login page and the following in the httpd error_log. This is a Centos 7.9 server with PHP 7.4. Could someone help me understand what these errors mean, taken from /var/log/httpd/error_log?
    Code:

    Do an ISPConfig update with:

    ispconfig_update.sh

    to see if the error persists. If it persists, then check if you really use PHP 7.4 and not PHP 8.

    Should I use --force? Now I'm wondering if something got corrupt.

    Like the message tells you: If you are sure you want to update to stable anyway, please use --force parameter
    so:
    Code:
    ispconfig_update.sh --force

    Yes, please use --force. Missed to add that to the command.

    I reinstalled with --force and I'm still getting the same result. What else could I check? And thank you both for the assistance so far.
    I took a look at the code in the file and I don't understand why PHP is throwing these errors. Unless there's an order of operations issue. But app::load() looks defined to me!?!? Looks like line 64 is loading database files with $this->load(). Why does PHP think it's not defined? Hmmm...?

    What is the output of
    Code:
    ls -la /etc/alternatives/ph*
     
  10. rwheindl

    No such file or directory.

    Maybe it's
    Code:
    ls -la /var/lib/alternatives/ph*
    on CentOS?

    /var/lib/alternatives does exist, so does /etc/alternatives, but also: No such file or directory.

    What is your php-cgi --version output?

    That's ok for a CentOS system, this is a mechanism that exists on Debian and Ubuntu only.

    That's strange indeed and I have not seen that on another system yet.

    Looks the same as php -v

    I'll look through other logs to see if I can find anything useful that might be related.

    After fixing the permissions on config.inc.php (changed from 600 to 750). I'm working through this new permission error that showed up.

    I'm going to compare file and directory permissions with another working ISPConfig server.

    Before altering permissions of files, I would first verify the script is running as the correct user.

    What's the best way to check that? I don't know how to find that out.
    I changed the file back to 600 perms. It was 600 on my other working server. This is the directory output where the index page sits. Based on this I'm guessing it's supposed to run as the "ispconfig" user? Or should it be running as apache?

    I supposed the easiest way is to update ISPConfig as root as I think that will overwrite all ISPConfig files and folders to default users and permissions?
