I see Double

On the homepage i see everything in double.

See the picture or see http://busimatch.com

What can be the problem and how to resolve?

OK, so the home page has double blocks of the same content.  What have you done, what changes have you made?  What modules have you installed?  Have you done any direct changes on the database?  What about the home page in the builders?  Are they double there as well? 

It's ok...

I found 2x   __page_main_code__   in template1.html :-)
