Sorry for bugging you all this much, but I've been working all day to make a tagging plugin work. The Simple Tagging is not working due to whitespace i category names (have them converted). The Ultimate tagworrior is working almost fine, but it causes a crash in my post.php, so that my inline file uploader is not showing. It looks like the output in 'ultimate_display_tag_widget' causes the crash.
I'm lost here, and I ask you - please give me some ideas of what to do.
