Dear support,
This is my server.

I do not have such income and traffic for switching to VPS. But I understand you, I know it would be better.
Forget the first three questions. The site was working before the upgrade, I'm not an expert to know is it your template or VirtueMart.
I followed your instructions to install the template
and I did not touch anything else.
The fourth question was related to shopping cart. My hosting provider has visited my website today, He tried to buy something, but he failed. Each category shows him only products from that category in the shopping cart, not from others. I was also watching what he try to buy, at home on my PC, I saw his cart and products. Try to go two at a time on my website and put something in the basket, and just look.
If it has to do with speed, then OK, first thing tomorrow I go to VPS.
Sorry for my bad English!
Regards,
Damir
