Opencart cart not updating?

Question

opencart

When adding a product, the Opencart cart, version 1.5.6.1, is not updated only after the page is reloaded.
I've already dug everywhere, re-read a bunch of forums, I don't know what to do already.
The most interesting thing is that, for example, when ordering Pizza, when choosing options, the cart is updated, but instead of my text it writes: Goods and price. I don't even know where he gets it from.
Turned off the vQmod modules one by one, apparently this is not the problem.
Thank you all in advance! Site vkusno31.ru

Answer 1

There was a similar problem.
Memcache was installed and session saving in memcache was enabled, this can be turned off in the memcache setting.
Open console in browser and monitor xhr requests.
