The following elements of the database are incorrect: Column xf_profile_post_comment.message_state missing. Column xf_profile_post_comment.likes missing. Column xf_profile_post_comment.like_users missing. Column xf_profile_post_comment.warning_id missing. Column xf_profile_post_comment.warning_message 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. See these threads/posts for more information and how to resolve it: XF 1.5 - Unable to Like Profile Post Comments Comment Like [Paid] I'll keep this post updated with any relevant information.
