My Question or Issue

 

I want to submit an idea. After having filled out everything (subject, post, tags, and chosen labels) and clicking "POST" my post is always rejected with the error message: "Correct the highlighted errors and try again."

 

But there are no errors highlighted, so I don't know how to solve the problem.
