Forms in sidebar not working

I really hope someone can help me with this since anytime I ask a question lately I get no response and end up solving it on my own… but this one I can’t!

I have a GetResponse plugin widget in my sidebar that allows someone to subscribe at my website. I have also added a registration form widget as well. The forms for either of them are not working. I have the confirmation URL for the GR one set to http://storyboutagirl.org/thank-you/ which is a valid and working URL. When entering my email and clicking submit I am forwarded back to my homepage and nothing is added to my GR account. And the URL showing in the address bar up top comes out like this:

http://storyboutagirl.org/?s=&custom_http_referer=/&confirmation_url=http://storyboutagirl.org/thank-you/&campaign_name=storyboutagirlorg&custom_ref=side&subscriber_name=Friend&subscriber_email=kirsten.adam%40implix.com

I thought it was the plugin. However I also added the “Registration Widget” plugin from the wordpress plugins directory and this is doing the same thing. It will not work. I have no other issues with forms in pages or posts or comments. Only my sidebar. It does not affect my search form under the squirrel however. Only ones after that. Can anyone help me figure out what the issue is?
