I have a website that we moved to hostgator because there were some simple support issues with the other host. However, the speed was ok there.
With hostgator the speed started getting really bad so hostgator had us install wp super cache. At this point we started losing images on the site.
Eventually we figured out we could get the images back just by updating pages where they were missing. The speed seemed pretty good too. Yesterday I activated wp super cache again. Today the site is substantially slower and images are disappearing again.
I can't find anyone that can tell me how to fix this. I'm not a programmer and I'm just not sure what to do now. It's a custom theme and everything I read tells me it's a tim thumb issue. Any suggestions? I'd appreciate any help I can get. I believe right now the images are all back but at one point many of the products showed no images at all.
