I keep getting the folowing error message whenever I try to create a private/locked sub category but have no idea what this error message means or how to fix it?
> Any group that is allowed to access a subcategory must also be allowed to access the parent category. The following groups have access to one of the subcategories, but no access to parent category: admins, moderators

When giving the group access to a sub-category they first need to have access to the parent category. For example for people to have access to #howto:faq they first need to have access to #howto the parent category.

Thanks for clearing that up, I tried again before seeing your post and accidentally created that sub category as a main category.
I am now trying to delete that category but I keep getting an “oops page not found” message whenever I try to click on the edit button to delete it.
Not sure how I can fix that issue up either.

Try going to the home page of the forums and then navigating back to the category to delete it.
