I'm using CloudFlare on my shared host. Recently all search engines and is-it-up sites have been getting a 500 error. I'm not sure who's to blame, my host or CloudFlare. I don't remember changing anything.
How should I start to diagnose this?
Has anyone experienced any 500 errors from CloudFlare?
Edit: The browser gets a 500 error too, but that 500 error returns the content of the website.
