thank you John,

I believe it is a clash with the theme.
I have taken over a site and am manoeuvring around what has been done.
my client wants her site to be responsive. Sadly the theme that is being used IS responsive but it doesnt look when I choose the pre built responsive layout.
Thats why I bought Responsivizer.
The template is a Rocket Theme template. Should I open a new thread? or maybe you have some insight already to a potential conflict between responsive themes.

Cheers
