cart and more price problem

Greetings,

Problems with cart, adding products but unfortunately nothing is added, so cart is always empty.
Ajax is enabled

Also we are getting multiple prices for same product, all price variants are showing.

Price is only visible to registered user.

Also, why is title on home page: StoreFront responsive multipurpose VirtueMart Joomla template - Juliana Nails | Kynsilakat, geelit nokgte!

I change it in admin area.

Hi

Title of page needs to be changed in menu item settings for Home item.

Site is offline, so please send me an access to it so I'll be able to check cart problem.
