So out of nowhere, my direct messages won't load on my site. I'm not sure what may have changed or what could be causing this but I now get this screen when trying to read PM's.

How would I go about fixing this or rather finding out what could be causing it? I haven't added any add-ons recently or made any changes to my site.
I doubt this is a host issue because this is the only page that does not seem to be working.
