Hi everyone, I had a problem when I installed addons Thread Thumbnails by Waindigo, Waindigo suggestted me posting here and looking for someone can help me solve the problems. Code: An exception occurred: Mysqli prepare error: MySQL server has gone away in /home/nintendo/domains/nintendovn.com/public_html/forum/library/Zend/Db/Statement/Mysqli.php on line 77 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 Zend/Db/Adapter/Abstract.php at line 825 Zend_Db_Adapter_Abstract->fetchOne() in XenForo/Error.php at line 48 XenForo_Error::unexpectedException() in XenForo/Application.php at line 309 XenForo_Application::handleException() Waindigo recommended me to disable all add-ons and tried to check off all options, after that I enabled the add-on again, but I didn't still fix it. If you have any advice, please give me or any suggestion replacement add-ons. Thank you in advance. Likan.
