Text being added after body…

Hello, I have spent most of my day on this problem, and can not find the solution.

The problem is that there is hidden text showing up after the body tag and before my first div-id

I can not figure out where it is coming from, however I have narrowed it down to the theme.

The theme is an RT-Theme, and when I change it to the twenty tweleve theme the text disappears. I’m guessing the code is being called by a script somewhere, and being told to insert itself after the body tag.

This is the website, http://customdoorshop.com/, the text in question can only be seen by viewing the html. It was visible via IE, but as far as I can tell it can’t be seen with any browser at this point.

I really just want to close the job out for this client, and rebuilding their site is not in the cards for the price I gave them to fix it.
