Ошибка DLE Forum

После установки модуля такая ошибка
MySQL error in file: /engine/forum/admin/forum.php at line 50
Error Number: 1146
The Error returned was:
Table 'a80618_1997.dle_forum_posts' doesn't exist
SQL query:

SELECT COUNT(*) as count FROM dle_forum_posts
и вот 50 строка кода

$row = $db->super_query("SELECT COUNT(*) as count FROM " . PREFIX . "_forum_posts");
