Woocommerce product page navigation is broken

Update: This is a duplicate thread and original you can find here.

Hi, for some reason the navigation that appears at the bottom, when there’s enough products to constitute at least a second page, doesn’t want to work when you click on the links.

Also on the this page, the third/last row of products end halfway through the row

The only thing I’ve really done, coding-wise, is insert custom css, although it wouldn’t make sense that I may have done something wrong to break it with CSS.

Also, I’m not sure if I should query it with you or Woocommerce.

Would someone mind having a look for me and advising please at the following URL d-base.dyndns.biz/bolus/?product_cat=performance-series.

Much appreciated.
Regards, Mario.
