500 errors when entering domain.com/cpanel

You are getting an forbidden message. it means that accessing to your file / folder you are trying to open have been denied. Misconfigurations and bad system or / and security and / or  firewall settings can cause this error.

All the directory listing whether the directory listing is shown is always determined by "Indexes" in Main >> Service Configuration >> Apache Configuration >> Global Configuration. From your description and errors, the box next to "Indexes" is probably not checked on your server, this might be the error since you receive memory errors

and many co-related errors.

Hello Emma,

Check if there are any errors showing in /usr/local/cpanel/logs/error_log location when trying to access cPanel. After you have verified that,you will need to check WHM > Tweak Settings for the Max cPanel Process Memory value and check what is shown there to get a clue of what could be the cause of the error message.

The quickest way to solve those problems that you are getting will be by looking at the following logs:

/usr/local/apache/logs/error_log

/usr/local/apache/logs/suphp.log

Or you can alternatively look at the following:
ps faux
ps faux |grep username
kill -9 pid

 

Hope this helps.

Regards,

Carl
