Can't add tags to questions
I can't add tags to questions: neither from the front end (question form menu item) nor when editing a question from the back office.
I can select a tag but after saving, the question doesn't hold any tag.
Plus: sometimes when adding a tag, for instance when selecting tags in Tagged items menu item, or when trying to add a tag to a question as said above, not all the available tags are shown, some of them are often missing.
Plus: I noticed that if you go to CA Configuration - Questions at the bottom of the page there is Show Tags: if you click on Show then save, Show doesn't get selected, same with Hide.
I am using CA 5.3.4, CjLib 3.2.5, Joomla 4.0.4
I'd appreciate your help.
