Ok so I think I found the problem
Not sure if im doing this the correct way, but when I made my shop home page from the Dashboard >> Add Page I added a description in the shop page
I also just added an image to test to see what happens, its ading cufon / styles to everything I add in the description area.
Now ive noticed that in the woocommerce theme config.php file the page-description attribute is falling in between the following function. If I remove one of the classes from the div it fixes it, but removes the cufon from everywhere else :-/
echo '<div class="post-title big_title bg_gallery cufon_headings">';
Wondering if there is anyway to cancel it out via CSS, or add a description else where, I wanted to use that area to display discounts and latest offers ect...
