I just tried to install the Charm style, and got the following error: Code: An exception occurred: Mysqli prepare error: MySQL server has gone away in /var/www/vhosts/mydomain.com/httpdocs/dev/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 XenForo/Model.php at line 219 XenForo_Model->fetchAllKeyed() in XenForo/Model/RoutePrefix.php at line 41 XenForo_Model_RoutePrefix->getPrefixesByRouteType() in XenForo/Model/RoutePrefix.php at line 54 XenForo_Model_RoutePrefix->getPrefixesForRouteCache() in XenForo/Link.php at line 487 XenForo_Link::_loadHandlerInfoForGroup() in XenForo/Link.php at line 404 XenForo_Link::_getPrefixHandler() in XenForo/Link.php at line 370 XenForo_Link::_buildLink() in XenForo/Link.php at line 97 XenForo_Link::buildPublicLink() in XenForo/Dependencies/Admin.php at line 197 XenForo_Dependencies_Admin->getEffectiveContainerParams() in XenForo/FrontController.php at line 635 XenForo_FrontController->renderView() in XenForo/FrontController.php at line 158 XenForo_FrontController->run() in /var/www/vhosts/mydomain.com/httpdocs/dev/admin.php at line 13 I assumed it was a problem with the style, so posted in the relevant thread, but the style author has said it is unrelated and asked me to post a new thread here. Just before I attempted this, I upgraded my forum from 1.4.5 to 1.5.1 with no problems. I then updated the styles Soft Responsive, Soft Responsive Coffee Edition, and Latte - all with no problems. Attempting to install Charm from scratch, though (as a new style, no parent) gives the above error. Can anyone help? Thanks.
