Before I really dive into things I was just curious if anyone else has run into/knows what causes this particular error when upgrading to 1.2 beta 3... Uh oh, your upgrade to 1.2.0 Beta 3 has failed! The following elements of the database are incorrect: Column xf_forum.allowed_watch_notifications missing. Column xf_forum.default_sort_order missing. Column xf_forum.default_sort_direction missing. This is likely caused by an add-on conflict. You may need to restore a backup, remove the offending add-on data from the database, and retry the upgrade. Contact support if you are not sure how to proceed.
