Warning Message

When a subscriber goes to…

http://aboriginalarts.org/wp-admin/my-sites.php

There is the following message…

Warning: Missing argument 2 for wpdb::prepare(), called in /home/ilance/aboriginalarts.org/html/wordpress/wp-content/plugins/limit-blogs-per-user/limit-bogs-per-user.php on line 112 and defined in /home/ilance/aboriginalarts.org/html/wordpress/wp-includes/wp-db.php on line 990

Also there is a link to an empty aboriginalarts.org dashboard.

1. How do you fix the warnibg message?

2. How do i remove the aboriginalarts link?

I am using limit-blogs-per-user set at 1.

Thanks Jeremy
