Template Error Help

Ahh, Good old Internet Explorer. The main enemy of many developers around the world. Does anyone know what could have caused my website to turn into this when browsing in IE? The site works fine in Google Chrome and such, only IE is like this. Please help! Thank you!

Well. Facebook connect is not working, and i can't use the join for either. Says my country is blocked. I am in the USA.

Anyhow. I would look down at the lower right of your home page where the shoutbox is.

Look at the right side of the shoutbox. Border is missing and that is a visible problem in bother IE and firefox. So your problems are beginning somewhere in that area.

But without being able to signup, i can't get logged in to get to a page that has a menu.

Sorry Man, I completely didn't realize that the user has to log in to see the menu. I have allowed sign ups from the US for now, but will close that eventually tonight as I do not want many people to join until the site is launched. And let me know if the issue is present in Google Chrome or Firefox because I cant seem to reproduce the error in these browsers. Thanks!

You must have missed the part i mentioned about the shoutbox. That problem does show up in firefox.

It's not the shoutbox because the same error is accruing on every page of my site.

Perhaps not. But there is still something wrong with it.

Now. This search bar that shows up under the breadcrumbs. It's there in firefox, but not in IE.

Because i cannot find anything obvious i would start with things you have added such as that search bar.
