Loss of styling - CSS on Hikashop update

Hi,

We have a development site where we have just updated Hikashop to 3.01.

For no obvious reason, the category and product displays have lost their formatting and will only display as lists. Before the update, they were displaying perfectly.

It now looks as if some element of CSS is not being applied. I have raised a ticket with the template supplier as well, but would be grateful if you recognise this problem and have any suggestions.

Many thanks


Richard

thank you so much, Nicolas. I thought it had to be something obvious.

Best wishes


Richard
