500 Internal Server Error

[JonathanY]

My plesk just updated automatically this morning and now I am receiving 500 Internal Server Errors on all the PHP pages.

It also changed the directory of my where my domain is hosted. Previously the site was located at /var/www now it is located at /var/www/vhosts/domain.com/httpdocs

I'm not sure why it updated my file path but I have tried removing the .htaccess files already.

Any ideas on how I can troubleshoot this? Everything was working fine last night, and after update, I cannot see any PHP pages.

If i need to check an error log, please tell me the location, because I am confused to where the logs are when trying to find them :/

I am running plesk on debian.

What do you have for this:

tail -f /var/www/vhosts/domain.com/statistics/logs/error_log

With any of the domains displaying that error ?

Also, may I suggest you rebuild the vhosts?

/usr/local/psa/admin/sbin/httpdmng --reconfigure-all

Lastly do you have Nginx enabled or NOT?

This is what is displayed from the error_log

I rebuilt the vhosts, but no messages came up, it just waited a little and then the next line came up. Not sure if that's the way it works.

And Nginx is disabled from the Parallels Plesk panel.

How about?

tail -f /var/log/httpd/suexec_log

 

[JonathanY]

tail: cannot open `/var/log/httpd/suexec_log' for reading: No such file or directory

This is what I got, I don't have a httpd folder in /log/

:/

I did find suexe.log in /apache2/ directory using this: tail -f /var/log/apache2/suexec.log

[abdi]

Try:

chmod +x /var/www/cgi-bin/cgi_wrapper

 

[JonathanY]

I did that, still the 500 error and getting the same messages regarding the cgi_wrapper in the log file.

Edit: What are the permissions for the files and folders regarding cgi? The owners?

Thanks.
