I'm developing an online store using wp e-commerce plugin.

Whilst working on it locally the problem didn't occur, but after I started testing it online a large gap began appearing before the top of the page. Using Firebug I've been able to see that the styling causing it is: html {margin-top: 28px !important; }

which firebug is telling me comes from a file that has the same name as the page ie: if example.com/products-page is the page being viewed it says that the style in question is being created by http://example.com/products-page on (line63)

I have used dreamweaver to search the entire wordpress folder locally for the style causing the error but it doesn't exist - it seems to be only occurring when the site is live online. I considered that possibly something could be getting added at a server level so I uploaded the site to an account on a different host - but same problem.

I'm using a reset.css file that would normally overcome this style being recognised - but than !important is what keeps it from being ignored.

Any insights or suggestions greatly appreciated
