Hi there.
I did change to another theme. My site was non-functional and I couldn’t figure out what was wrong so I switched to another theme to make sure something was working.
GoDaddy said it might have something to do with your theme but even this one had the same message (but only once). I flushed the cache and it disappeared eventually. When I flushed the cache with your theme, nothing happened and the site still showed the error messages.
GoDaddy also mentioned it may also have to do with other plugins such as Facebook Open Graph but who knows. I needed my site up so I switched themes.
