Uh oh, your upgrade to 1.2.0 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. I have the following addons: custom bbcode manager 126.96.36.199 keycaptcha 2.1 last post avatar by waindigo 1.1.6 nodes as tabs 1.1.4 online status 1.1 pinit share button 1.0 social beta 2 template modification system 1.2 thread thumbnails by waindigo 1.3.1 top posters stats 1.0 xencarta 1.4.1 xenporta 1.5.8 tagme 1.7.2 widget framework 2.1.1 xentag 1.6.5 custom node icon 0.9 Any idea which addon is causing this and how I should proceed?
