Hello !
In our menus that do not have anything to do with cb is "com_comprofiler_tools" part of the url... Why?? That's not so good.
For example: We create a menu entry called magazine, that is linked to a category in k2. Url is looking like:
www.domain.de/com_comprofiler_tools/magazine.html
????????????
EDIT:
Already deinstalled cb, killed the folders, killed mysql entries and tables. And still all urls have com_comprofiler_tools in it... Oh my god, that's horrible...
