support anonymous connected users in login block

I read the README.txt from start to finish.

For some reason after installing the FB modules using the instructions in the read-me, my /admin page no longer works, neither does using the /?q=admin address. I have no idea what could cause this so I didn't want to play around with the code, was hoping someone here ran into the same issue. However I can still access all the options that are children to admin like create node etc, just not the /admin page itself.

Also it should be noted that, when adding the php code found at the end of the README.txt to the settings file, the ?> at the end of the code broke my site in both IE and firefox, i forgot the exact error but it basically just said the page could not be loaded. I solved the issue by removing the ?>

You can check out my implementation of the FB modules so far at: http://www.sewfresh.com
The connect to facebook button in the nav bar is just the included block, positioned using div and css. One option I wish this block had (or I wish I knew how to implement) is an option of what to do/display if a non-local user who is NOT signed into facebook clicks the button. As of right now it will ask them to sign into facebook, and then it reloads the page and nothing really happens, the button still appears and if they click it the page just reloads. Would be nice to either make the button dissappear if they arn't registered as a local user, or redirect them to the sign up page.

One last thing, it would appear this broke over night somehow as it was working perfectly before I went to sleep:
Now when you click the connect with facebook button and fill in your info, my website is then loaded in the FB pop-up window, the window doesnt close and reload the main page. Not sure why this happened.. and even though I'm logged in in this pop up window, in the main browser if I reload the page it still shows me as logged out.
I get this error when logged in as admin:
"The Facebook Application labeled SewFresh has a suspicious connect_url. The value is http://www.sewfresh.com/, while something starting with http://sewfresh.com was expected. Consider editing SewFresh."
