Category not displaying properly: All categories listed in a single column

Hi,

My category listing is using Div and 4x3 but when it displays, it is showing a single column with all the categories.

Thanks,
Saad

Thank you, Jerome.

I did deactivate the front css because it was creating an issue with the Templaza Jollyness template.
This was suggested by their support team to fix an issue related to the product listings.

I activated it again but I still get a signle column.

There seems to be quite few conflicts between this template and Hikashop or I might be doing few things wrong.
Ex. When I open a category, the products are not listed although there are plenty of products in those categories.
Please note that I had Hikashop installed for quite some time but now that i upgraded the version along Joomla and added a new recommended template, everything seems to be broken.

Thanks,
Saad

I am having the same problem. This has destroyed a lot of work on the website, and is driving customers away.
