miniK2StoreCart sometimes doesn't appear...

I need help for a problem about
miniK2StoreCart with the template gk restaurant.

I have already tried to exclude all js effects
that could create conflict, but I am not able to find the
problem that causes the cart to disappear randomly. I try to emptying the cache
and
sometimes it reappears, then browsing through the pages, the function
crashes again and the cart desappear.

I noticed that the cart is loaded lately
through a js function, maybe it would be better
to apply the code directly in the file default.php
Module "mod_k2store_cart" or
do you think it might be useful to update the entire K2Store from 3.0.3 version
to 3.6.0?

Thank you very much for your help

Console says that there is a problem to access to ajax view for this cart :

Code: Select all

XMLHttpRequest cannot load http://bcomebaccala.com/index.php?option=com_k2store&view=mycart&task=ajaxmini. Origin http://www.bcomebaccala.com is not allowed by Access-Control-Allow-Origin.

Please try to contact with your hosting because this is probably related with you server security configuration .

Thank you for your answer I get in touch directly with my hosting support but as I imagined they answered me there is not a real indication about what is the real problem so I am asking you if you can specify better where is the problem in order to let me talk clearly with my support.
Thank you again for your help

The only description that I can give you is that what I've paste in previous response. I'm not a hosting expert, please try to install package on localhost and check whether the same happen.
