I accidentally deleted my footer... I was trying to edit it, but no nothing about coding, so that was silly. I have deactivated jetpack and reactivated it, and that didn't seem to help....
To solve the issue, you will need to revert to a previous version of your theme, where the footer still exists.
You should be able to download a fresh version of your theme here:
