홈피 업데 후 오류가 뜨며 접속이 안됍니다

최신버전 rhymix-2.1.27 파일 업로드 중 마지막 쯤에 Dedug.php에 오류가 있다는 내용이 살짝 보이길래 문제가 있나보다 했습니다

마치고  보니 역시 아래와 같은 오류가 뜨며 접속이 안됍니다

Fatal error: Uncaught Rhymix\Framework\Exceptions\DBError: SQLSTATE[HY000] [1045] Access denied for user 'yjoon'@'localhost' (using password: YES) in /hosting/yjoon/html/common/framework/DB.php:143 Stack trace: #0 /hosting/yjoon/html/common/framework/DB.php(110): Rhymix\Framework\DB->connect() #1 /hosting/yjoon/html/common/framework/DB.php(78): Rhymix\Framework\DB->__construct() #2 /hosting/yjoon/html/common/legacy.php(197): Rhymix\Framework\DB::getInstance() #3 /hosting/yjoon/html/modules/module/module.model.php(1077): executeQuery() #4 /hosting/yjoon/html/modules/message/message.view.php(16): ModuleModel::getModuleConfig() #5 /hosting/yjoon/html/classes/context/Context.class.php(1666): MessageView->dispMessage() #6 /hosting/yjoon/html/common/framework/Debug.php(787): Context::displayErrorPage() #7 /hosting/yjoon/html/common/framework/Debug.php(660): Rhymix\Framework\Debug::displayErrorScreen() #8 [internal function]: Rhymix\Framework\Debug::exceptionHandler() #9 {main} thrown in /hosting/yjoon/html/common/framework/DB.php on line 143

해결 방법이 있을까요?

부탁드립니다
