Products not displaying in 3 columns

[elecpulp]

On the store homepage view and category view for the following site:

http://shoetreat.com

my products are only displaying 1 product across, instead of in 3 columns.

This is a recent problem after I updated my store with new merchants. I have the following code:

<div class="t1 col3">

in all the relevant places and up until the last store update, the site was displaying perfectly.

Can you please shed some light on this?

In fact, on further inspection, it appears that none of my "views" are recognising the "col3" code.....

You appear to be missing the datafeedr style.css file. Try changing the "CSS file" field to shop/style.css in your URL Settings.

That worked a treat! Thank you, Eric!
