Is there a way to unhide or edit the footer in Squarespace when the "hide footer" code was (accidentally) put into the footer?

I accidentally pasted my "hide header footer - always" code INTO the footer of my site on Sqaurespace.

Now, I can't edit those sections to remove it so my shopping cart is inaccessible.

Help!

I've tried adding override code into my custom CSS and Code Injection using !important,but unfortunately, i think the original code also already contained "!important"
