Problem with saving URL Rewriting setttings

Hey,

this is kind of a weird problem. Whenever I save the new URL RW settings of new added functions in vb (i.e. tags), it does not save it and replaces the new settings with default ones (i.e. VBSEO_URL_TAGS_HOME). I even tried to disable it but that even does not work. The file config_vbseo is chmod to 666.

never mind, I think I figured out the problem.
