Automatically is hidden by BSS


As you can see

As you can see, "subscriber-promo" has "rgosopn" & "hidden" applied to it even though didn't add it. "rgosopn" & "hidden" hides the content from view. This has happened to three div blocks on my website. Is there any way to stop this?

If in your project in BSS it is not there, but it is when you preview the site, the most likely reason then would be that a script is modifying the page. With ifame there for twitter I'm suspecting that's the cause. If you remove the iframe would that then still be happening. If it doesn't then you know what the cause is. What to do about it, that's hard to say. Try a different class name, one that doesn't include header or wrap or even a div rather than header element.
