Thank you, skbcgn! Do you have the premium version of Knowlege Base? I think i don’t have that setting “Category Slug” in my free version. But the problem didn’t show up for several weeks, so i hope it stays so 😉
Also i don’t understand why it is not allowed to write that you had the same problem. Actually that is the purpose of such a forum not to open up new threads for the same problem. I thought 🙂
