Very strange. I switched hosts last night. Everything was working fine before I went to bed. I wake up, login and now cannot edit any of my product descriptions. I cannot even click inside the content window. none of the edit links in the Publish box work as well as most links in other sections, such as the featured image section.
Thought it might have been a permission issue, but everything is fine, I'm an admin. Also cleared out all my cache.
I have a suspicion that the host may have updated wordpress. But I cannot remember what version I was on at the time.
All I can do is re-upload the site and hope it works.
