Hello, I installed the free version of hikashop on my site. I am using joomla 3.3. I've seen a big difference in skin compared to 2.5. You see it all very small and badly positioned. Can anyone tell me why?
thanks

Looks like you're using Hathor as Joomla backend template. Switch to Isis as default, and it'll all look much better.

Thank you very much, so I solved the problem by
