I have spoken to my host 3 times now. The first time they recommended uninstalling a website accelerator. The 2nd time they said they couldn’t help me.
I just called again and the consensus was that I either needed to completely reinstall wordpress or perhaps when I updated to 3.5.2 that it didn’t complete.
I managed to upgrade to 3.5.2 from my hosting panel, which didn’t help.
I’ve also realized that I cannot access any of my other wordpress installations. They’re all hosted together but separate installations and domains.
