I needed to hide Category assignment when user is creating a content. I installed Taxonomy Access Control module, which worked, but then realized I have to have default Category assigned on these nodes, or these user-created nodes get lost in the long list of contents list (I much liked Joomla's content admin filter design).
So, I installed Taxonomy Default module, only to realize I, the admin also loose access to Category assignment. I disengaged Taxonomy Default module from the module list, not really understanding what needs to be done to uninstall, I found Taxonomy Access module no longer works. No matter what setting I change, the result is unaffected.
Something went wrong. At this point, I am happy if Category assignment fields disappeared from Create Content on users. Any help would be very much appreciated.
