Hey folks, It seems that for some reason now, I'm unable to rebuild the search index, and the index itself isn't getting updated properly as posts are made on the board. When I try to rebuild, I'm getting this error: Code: Server Error Mysqli prepare error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1 INTO xf_search_index (content_type, content_id, title, message, meta' at line 1 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/Search/SourceHandler/MySqlFt.php at line 110 XenForo_Search_SourceHandler_MySqlFt->_pushToIndex() in XenForo/Search/SourceHandler/MySqlFt.php at line 74 XenForo_Search_SourceHandler_MySqlFt->insertIntoIndex() in XenForo/Search/Indexer.php at line 44 XenForo_Search_Indexer->insertIntoIndex() in XenForo/Search/DataHandler/Post.php at line 51 XenForo_Search_DataHandler_Post->_insertIntoIndex() in XenForo/Search/DataHandler/Abstract.php at line 227 XenForo_Search_DataHandler_Abstract->insertIntoIndex() in XenForo/Search/DataHandler/Post.php at line 123 XenForo_Search_DataHandler_Post->quickIndex() in XenForo/Search/DataHandler/Post.php at line 93 XenForo_Search_DataHandler_Post->rebuildIndex() in XenForo/CacheRebuilder/SearchIndex.php at line 91 XenForo_CacheRebuilder_SearchIndex->rebuild() in XenForo/ControllerHelper/CacheRebuild.php at line 26 XenForo_ControllerHelper_CacheRebuild->rebuildCache() in XenForo/ControllerAdmin/Tools.php at line 78 XenForo_ControllerAdmin_Tools->actionCacheRebuild() in XenForo/FrontController.php at line 312 XenForo_FrontController->dispatch() in XenForo/FrontController.php at line 132 XenForo_FrontController->run() in /home/rpdom/public_html/admin.php at line 13 The only change I know has been made recently is a move from MySQL 5.5 to MySQL 5.6 with InnoDB tables across the board. However, I have converted the xf_search_index table back to MyISAM and it still throws the same error, so it doesn't seem to be engine related. I have also tried disabling all addons and running the rebuild with the same result. Any ideas on this? Thanks.
