I use multisites and have a new site that is acting screwy. On my products listing page I have 3 columns
Left Has: Categories List, Latest Products
Middle Has: Special Offer, Products Breadcrumb, and Products list
Right Has: Products Search Form, Small Cart, Products Recently Viewed.
When using the categories list to filter through products, when I get to the bottom sub-category in any category the left column disappears and I just am left with the Middle column and the Right column which shift over and leave a blank space on the right.
I have 4 sites running. this only happens on one of the sites. It is driving me nuts.
