Question Errors during loading homepages

[msauer75]

Hi,

I found this post Websites are loading slowly or fail to load with a 50x error: mod_fcgid: can't apply process slot for /var/www/cgi-bin/cgi_wrapper/cgi_wrapper
but the solution doesn't work. What can I do that the site work correct again?

Thank you for your help.

Websites and ActiveSync services hosted in Plesk are loading slowly or fail to load with a 50x error: mod_fcgid: can't apply process slot for /var/www/cgi-bin/cgi_wrapper/cgi_wrapper

Applicable to: Plesk for Linux Symptoms Websites are loading very slow or loading continuously and eventually fail with a 50x error in a web-browser: 500 Internal Server 502 Bad Gateway 503 ...

is the correct approach. If problems persist after that, other factors play into it. First solve the first, then proceed with the next issue. But for sure, resources are insufficient, so you should start with the CGI settings first.
