problems when the page is displayed

Hello, I installed the Event Registration Pro component to allow users to reserve and purchase trekking events, which is the subject of the site.
When this component is deployed, exceeds some modules of the template and is hidden.
My computer support tells me that is due to the template calculates a maximum of 1500px in the body, but it needs to be "auto" , in order tu addaptate automatically its dimension in every case.
Could you tell us, pls., which javascript line is necessary to modify for solving this problem?
Thanks

Please give us link of your site so we can inspect the problem. Did you try to solve it by disabling rotating background in template parameters?

Thanks, Milos. Our website address: www.artrosys.com
We didn´t. I´ll tell that to our technical support.
Thank you

Hi again, Milos. Can´t find "rotating background in template parameters". Background type in our template is on "static image". Is that what are you refering to?.
Thanks

What is is exact link where that component resides, on home page there are no java script conflicts
