My site, http://www.connectedrepublic.co.uk keeps getting random Internal Server errors, and my hosting company (UK2.net) believed it's due to hitting my CPU usage limits.
They've told me to have a look through my scripts to make sure they're all functioning properly, but I'm not a developer, I just use highly rated plugins and a paid theme.
I was considering deactivating all the plugins and activating them one by one until I find one that is causing the problem, but the Internal Server errors are so random and difficult to recreate.
Does anyone have any suggestions on what I should do?
