WordPress automatically points to Google Apps login – Help!

Our organization uses WordPress for its site (https://www.illowaima.com) and Google Apps for our chapter e-mail addresses. I attempted to embed the HTML code for our organization’s calendar in agenda form in a text-based widget, and I also tried to embed the calendar in monthly form on one page. Ever since I tried to do this, the website automatically redirects to our Google Apps login screen.

I cannot get into my WordPress admin screen to remove the text-based widget. Has anyone else had this problem? What did you do to resolve it? Finally, how can I embed a Google Apps calendar on WordPress so this does not happen again?

Thanks!
