Deprecated: has_cap

Hi,

iI got an error:

Notice: has_cap was called with an argument that is deprecated. since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /var/www/html/exoblog/wp-includes/functions.php on line 3570

Could you check it?

Thanks,
Lam
