Check my tutorial about using phpmyadmin via cpanel. From there navigate to the sed_config table and locate the row that looks like it's maintenance mode. Turn it to 0.

Alternatively you could rename the plugin folder to plugins2 and see if that's causing the issue. If one of the plugins is causing it then just try renaming them all and renaming them back.

In any case, you should be able to log in to your site in maintenance mode if you're an admin.
