Can't delete subject

[erigo19]

When i select a subject on my forum and after that try to delete it i get a message that i haven't select a subject. The subject is light yellow before i try to delete it.
How can i solve this problem.

Can you printscreen exactly which value you're editing? There's a few places a 'subject' can be changed.

I get this as admin, as moderator etc. So someone post something on my forum that i don't like an try to remove it. I select it and after that i try to remove it.
