I've been running Xenforo for a while now and never come across this problem until end of last week:
An exception occurred: Mysqli statement execute error : Prepared statement needs to be re-prepared in /home/jpbsuppo/public_html/forums/library/Zend/Db/Statement/Mysqli.php on line 214 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 825 Zend_Db_Adapter_Abstract->fetchOne() in XenForo/Error.php at line 55 XenForo_Error::unexpectedException() in XenForo/Application.php at line 363 XenForo_Application::handleException()
The forum isn't heavily active - maybe 3 posts a day (we're about to launch our first paintball marker - will pick up after that!).
Any ideas? Thanks
