Marketpress styling issues....

Hi,

Still trying to tame styles with Marketpress.
How can I get Marketpress showing pages as it must?
First it was said it is/was a conflit between Marketpress and the theme (Customizr) I was using, but even with Simplemarket theme I am not able to see my cart, I am not able to cloe a transaction.
I do want to use Customizr theme (I want to have a concise site- all my other pages/subsites uses this theme). The devs of it have given me some codes to clean some issues but it is still not working properly.

I am also granting access to this site....

Thanks!!!!

Ps: I am opening a new thread instead of using the old one in order to avoid misunderstandigs.
