If I try to redirect a thread and then set the redirection expiry to something large like 9999 months or weeks, I get the following error: Code: Server Error Mysqli statement execute error : Out of range value for column 'expiry_date' at row 1 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 Zend/Db/Adapter/Abstract.php at line 574 Zend_Db_Adapter_Abstract->insert() in XenForo/Model/ThreadRedirect.php at line 136 XenForo_Model_ThreadRedirect->insertThreadRedirect() in XenForo/Model/ThreadRedirect.php at line 112 XenForo_Model_ThreadRedirect->createRedirectThread() in XenForo/ControllerPublic/Thread.php at line 1252 XenForo_ControllerPublic_Thread->actionMove() in XenForo/FrontController.php at line 347 XenForo_FrontController->dispatch() in XenForo/FrontController.php at line 134 XenForo_FrontController->run() in /var/www/vhosts/snrdev.seniorgamers.net/httpdocs/index.php at line 13 It appears that the date it doesn't like going past is Sun, 07 Feb 2106 06:28:16 GMT which, in unix time, is 4294967296. Why this number? This is 16^8. @Brogan isn't getting this error, so presumably it is some configuration or MySQL issue. Any idea what the configuration/MySQL issue might be and how to correct it? Also, is there something that can be changed in Xenforo itself to prevent getting an error or allowing for long redirection settings like this?
