Looks great, but lost default fonts

I created one landing page with this, and I was really happy with how it worked — it was easy to use, had nice design elements, etc. BUT, when I published the page, I lost all of my default fonts on my entire site. The landing page looked awesome, but my website looked blah.

I found that the easiest way to resolve this issue, since support didn’t answer my question within 24 hours, and I wasn’t willing to wait around longer than that with such a major design problem going on, was to delete the plugin, which I did. Too bad, because I think it has a lot of potential.
