Upfront doesn't recognize any html? (Panino)

I feel I must be missing something. I've literally been working to configure this theme for almost 18 hours, and I keep having to redo things over and over.

When I add a "code" element to a page, I should be able to run html, correct? I've tried embedding an Aweber opt in numerous times. When I click save, nothing shows up, and when I visit the code element again, the embed snippet is gone. I've saved over and over, and it disappears every time.

I've tried with other html as well, and similar things happen. Either nothing shows up, or the markup just disappears altogether. This has happened using the HTML tab, but I've also had similar issues with css and js. I have support access on the site enabled (uig.dangeroustactics.com). Any insight is much appreciated. Thank you.
