SEF not working with virtuemart

Yes ok, but I still don understand what do you reffer

So,
when you off the response, the template should work without any redefinition or follow any of the css of response, correct?
when i off it, because i faced some problems, like in menu not shown properly, carousel pro same... i still find that footer and content and most of the parts of the templates (also the zoom at the dimension of mobile template) still working.

look the snapshot i sent you, you can see how the content is limited in width. check it from your smartphone not from computer, the problem happen when you use a smartphone.
hope i was more clear,

thank you

No solutions?

Mobile browser have problems with fixed positioning and you have that face-book thing to right it looks like it pushes content

thank you for your answer, that fixed i added it recently, nothing to have with the problem, it was also before not only now.

thank you.
