Mike XenForo developer Staff member Jun 12, 2016 #2 I've responded to your ticket about this, but this is generally indicative of files not being uploaded as expected. You'll need to contact the add-ons authors to check that you've followed their specific packaging instructions though. Upvote 0 Downvote
