Thanks for your inquiry. ~ We appreciate your patience :-)

It appears this installation of WordPress is running several other plugins and a custom theme. Please put together a test installation that is running a default WordPress® installation. If the problem persists, please report back to us with that Dashboard login and we will investigate further.

NOTE: Upon review of your site, I find that all of your s2Member menu pages in the Dashboard are lacking some functionality. This is an indicator that you may have a conflicting plugin and/or a problem with your WordPress® configuration overall. Please put together a test installation running a default WP installation and we will investigate any remaining issues that you may have.
