database error
 

The only change I've made to the forums for months is an upgrade to 3.8.7pl3 yesterday.

I tried to change an inserted image then I received this message when submitting the edited post. By the way, the preview of the post worked fine.

Here's the error I received when trying to submit the edited post:
