MySQL Error!
MySQL error in file: /engine/modules/addcomments.php at line 218
Error Number: 1052
The Error returned was:
Column 'access' in field list is ambiguous
SQL query:

SELECT id, date, allow_comm, approve, access from dle_post LEFT JOIN dle_post_extras ON (dle_post.id=dle_post_extras.news_id) WHERE id='13'


Не могу понять в чем ошибка, можете исправить?
128 строка:
$row = $db->super_query( "SELECT id, date, allow_comm, approve, access from " . PREFIX . "_post LEFT JOIN " . PREFIX . "_post_extras ON (" . PREFIX . "_post.id=" . PREFIX . "_post_extras.news_id) WHERE id='$post_id'" );
