Hello,
For some reason, 'New Group' menu item and the 'New Group' button on the all-group page don't work anymore (which worked before) on my site, showing a message, "Category does not exist." Though the button on each category page works fine.
Then I logged-in as a super user... both the menu item and buttons work fine, showing category field as 'Uncategorized'.
I recently added/deleted some categories in GJ, but I don't remember if I deleted 'Uncategorized' category. Would this be possible and caused this problem???
Thank you.
