Additions to sidebar break footer

https://www.fifthbynorthwest.org/

Yesterday I tried to make the following changes to the sidebar at this site:
1. Add the Facbeook Fan Box
2. Add a MailChimp Newsletter Sign Up Form
3. Add a simple linked image

Each time, the addition of those widgets caused the footer to shift to the left completely. I also tried hard coding each of those things into the sidebar with the same effect.

Adding a standard widget like the archives did NOT break the footer.

This is an Elegant Themes theme – and I haven’t customized the sidebar or footer at all, and I did not customize any of the widgets I tried to add beyond the code spit out by the individual services.

Thoughts?
