Thank you so much for all your help Sam! Weirdly enough, I did all the steps that you gave me, and for some reason my site still didn’t work (it seemed like it should have though!) Fortunately, Blue Host had most of my site backed up, so now I just have to do a little bit of work to get back to where I was before.
Lesson learned though! I am going to be much more careful when editing my themes!
Thanks again for your help!
