HTML formatting lost on Instructable Answered
I use html to format my list of parts into a table, like this page. Recently the formatting was somehow lost on this page which is a bummer because it took a while to create the html. The page was fine for at least a year. I don't know exactly when the html was lost but I suspect it happened a few weeks ago (October 12th) when I edited a different page on the same instructable. It's possible that I edited the Instructable while my Pro membership was expired. I definitely did not edit the page with the html formatting.
OS: Linux Ubuntu 14.10
Browser: Chromium 37.0.2062.120
Is there any chance of reverting that page (or even the Instructable) back to a date before the HTML was stripped out?
