FastCGI or fcgi errors causing intermittent 404 error

Hi guys,

I’ve read through your “My site is slow. How to speed up my website?” troubleshoot article and agree that the server may offer too little resources, however I’d still like to give you feedback from my host companies tech support regarding the problem incase it helps you speed up the theme for everyone with some optimisation?

Their response:

“i have checked the server logs and I could see mod_fcgi errors for the site ‘socsa.org.za’. Please see below snippet.

We have already increased the fcgi parameters to the maximum value allowed in our shared servers. Unfortunately, we cannot increase the values further. If the issue persists, you may contact a developer to assist in optimizing the site to resolve this issue.”

Is there anything you could do to increase the performance of the theme and eliminate this 404 error?

Kind regards
