Cart Cached

[tomaa]

I USe Joomla 3.4.5 and Virtuemart 3.0.12

Since some time I noticed that the cart for guest shoppers is cached somewhere and I can not find the correct place to disable this.
If shopper 1 leaves the page without check out - shopper 2 will see the cart as soon he enter the page.
For registred users everything works find and I belive this is due to no caching?
Anybody who can guide me in right direction?

well .. what caches have you got enabled?

personally I use no caching on any VM sites

I thought I had all disabled but I realised I had System_Cache plugin enabled and when disable this plugin everything seems to work again.
I think this plugin is a core plugin?
If disable the plugin could I have some other disadvantages?

On a std install I only have system plugin-> System - Page Cache .. which I always leave unpublished

OK, thanks. My plugin could be from older Joomla as I have migrated the site.
