Suppoerter Plugin and Theme Options won't save

Ever since the update to 3.1, I have not been able to save some of the settings within my Supporter Plugin. I am able to update the settings, but am not able to update the plugin's or the themes options. When I make my selections and click SAVE it re-directs me to the sites home page and does not save the changes. Anyone have any suggestions here? I'm in desperate need to add a few themes to the supporters and I can't activate them since it won't save...

Everything is the most current build all the way around.

I've tried on three differnt browsers as well to verify it's not cookies, etc.

Thanks so much.
