I read this forum and came across a solution from support for managing tags.
I installed the WP phpMyAdmin and went to wp_wpforo_tags where I see them
However, I noticed that if I delete a tag here, it doesn't disappear from the forum, it still shows up on the results page etc, as if nothing happened.
Will I need to delete the topic and post itself in addition to deletion from phpAdmin for it to be deleted completely?
after deleting the tag from database, go to Dashboard > Forums > Dashboard and press Delete All Caches button.
Thanks, but where can I find prefix_wpforo_topics?
