I planned on updating a small bit of HTML in one of our themes (just replacing an image on the sidebar), and when I clicked on "Update File", all of the text in the theme disappeared. Thankfully I saved the text, but no matter how many times I tried to paste it back into the text box, it would disappear when updated. And of course, now the sidebar on our site is missing.
The website is http://www.toughpigs.com/
Thanks in advance for your help!
