Hello everyone,

I have an online shop with the Google Analytics code integrated through the Google Analytics module. My problem is because of the error "ga is not defined", the javascript does not ejecute completely. Because of this a background I have set to a banner that should be shown through a class I have added with jQuery is not seen.

The url of my shop is: https://www.publi2001.com

Thank you very much for your help!
