Hi there, Few days ago I experienced an issue with my server and since then xf_deferred is causing issues. Most annoying thing is that in the admin front-end I got this error: Code: Mysqli statement execute error : Can't find record in 'xf_deferred' Zend_Db_Statement_Mysqli->_execute() in Zend/Db/Statement.php at line 297 Zend_Db_Statement->execute() in Zend/Db/Adapter/Abstract.php at line 479 Zend_Db_Adapter_Abstract->query() in XenForo/Model/Deferred.php at line 111 XenForo_Model_Deferred->defer() in XenForo/Application.php at line 1455 XenForo_Application::defer() in XenForo/Model/Cron.php at line 398 XenForo_Model_Cron->updateMinimumNextRunTime() in XenForo/Model/Cron.php at line 421 XenForo_Model_Cron->retriggerCron() in XenForo/ControllerAdmin/Home.php at line 7 XenForo_ControllerAdmin_Home->actionIndex() in XenForo/FrontController.php at line 347 XenForo_FrontController->dispatch() in XenForo/FrontController.php at line 134 XenForo_FrontController->run() in /public_html/community/admin.php at line 13 I had the same issue when upgrading my forum but I just deleted the contents of the xf_deferred table and that allowed me to upgrade the board. Now xf_deferred has no rows but I still got the error in the admin panel. The issue seems to be in the process email bounces process, when I try to run that I get the error. I've tried rebuilding caches, repairing tables, etc... What should I do to fix this thing?
