SSpencer,
You can do what I did: Delete the WP-sentinel from your wordpress site and then go into the database and edit the Ban’s to removed your IP address. My hosting site uses PHPAdmin to edit the tables. Just be careful to remove only your IP address. If you don’t know it, it will be listed on the WP-Sentinel banned email that you likely were sent. The plugin itself will be in wp-content/plugins and will be named WP-Sentinel.
This was suggested in by FattyMattyBrewing and it worked perfectly for me.
Camu,
If you do not have something helpful to add then be quiet. Not everyone knows how modify a WP site outside of the Admin panel. Helpful posts are always welcome. Mocking is inappropriate.
