Hello I went to create a new post on my blog today (nerdsontherocks.com) and was greeted with this screen.
Now I can't create any content. Even doing test posts, it will just vanish. Can't edit the featured image or add any new images.
I've deactivated every plugin and tried with different accounts. I'm not quite sure what happened, we haven't made any changes to the site recently.
Any help would be appreciated.
