Well I may be sleep deprived but I was dumb and did not back up my files prior to starting this newest upgrade due to the fact I had no issues with the last upgrade. However I have an issue now. I got this error when upgrading Code: Uh oh, your upgrade to 1.5.0 has failed! 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. And that cases this error when you try to post on member's recent status update or try to visit a profile of a member Code: Server Error Mysqli prepare error: Unknown column 'profile_post_comment.message_state' in 'where clause' Zend_Db_Statement_Mysqli->_prepare() in Zend/Db/Statement.php at line 115 Zend_Db_Statement->__construct() in Zend/Db/Adapter/Mysqli.php at line 381 Zend_Db_Adapter_Mysqli->prepare() in Zend/Db/Adapter/Abstract.php at line 478 Zend_Db_Adapter_Abstract->query() in XenForo/Model.php at line 219 XenForo_Model->fetchAllKeyed() in XenForo/Model/ProfilePost.php at line 1100 XenForo_Model_ProfilePost->getProfilePostComments() in XenForo/Model/ProfilePost.php at line 1317 XenForo_Model_ProfilePost->addProfilePostCommentsToProfilePosts() in XenForo/ControllerPublic/Member.php at line 259 XenForo_ControllerPublic_Member->actionMember() in XenForo/FrontController.php at line 347 XenForo_FrontController->dispatch() in XenForo/FrontController.php at line 134 XenForo_FrontController->run() in /home/guiltyp/docs/xenforo/index.php at line 13 I removed anything that had appeared in the latter error that were addons and I have currently disabled all add ons I have. I probably should have done that prior to upgrading. Can get some help? I have a back up of my site from the last grade I did, which was back in April. If I replace my currently (and messed up) directory files, will I lose any information? (Like posts and members from after that last upgrade?) Thank you for your help in advance. I do feel like an utter dunce.
