There seems to be some problems for my blog when I try to post new posts. If I choose "New" + "Post" the screen says "Beep, beep, boop" with three bouncing balls. I have never seen this before. When going back to main page it says "An error occured while loading. Please refresh the page and try again".
When I try to add a new post or article from within the dashboard everything is as before.
Also when I try to edit article from the front end the same "Beep, Beep, Boop" appears. When editing from within the dashboard is works fine.
Do you know what is wrong?
I have done all the usual stuff, deleted cookies, logged off and on again.
