Failing that, ensure that the filesystem permissions on the extension's files are correct (must be readable by whatever operating-system user the webserver runs as, and/or by its group).

 If you are using phpBB 3.3.8 or later, *and* it is not working properly for you, see if any recent-ish communication at https://www.phpbb.com/community/viewtopic.php?t=2661331 or https://www.phpbb.com/customise/db/extension/rh_topic_tags/support addresses the issue yet. When reporting an issue, be as specific as possible; no one can read your mind, or your logs.
