Can't add items to the cart

[47diamonddistrict.com]

We added some new combinations for items on two of our stores and now we cannot add any items to our cart.

 

Here are our two stores url:

 

1) http://47diamonddistrict.com/prestashop/

2) http://47diamonddistrict.com/prestashop/naf

 

In the first store, if we go the the category Engagement Ring (http://47diamonddistrict.com/prestashop/index.php?id_category=32&controller=category) and click on "Add to Cart", it brings us back to the homepage. However, if you click on a specific item (http://47diamonddistrict.com/prestashop/index.php?id_product=47012&controller=product#/color-d/clarity-vs2/carat-050/cut-very_good/metal-14k_white_gold) and click "Add to cart", the item is being added to the shopping cart properly.

 

In the second store, no matter where you are in the store, if you click on the "Add to cart" icon, you see the item being added to the cart but it does not keep it in memory. Every time you refresh a page the cart its goes back to being empty.

 

Any idea how we can fix that?

Thanks

Have you checked your server log files?

In our error_log file we have a lot of this error:

 

ERROR: PREG_BACKTRACK_LIMIT_ERROR in function packJSinHTML

 

But this error started to occur way before the current issue we are having.

UPDATE: Finally it looks like a local problem, I tested on different computers and the shopping cart seems to be working fine. Also its only doing this in Chrome, the shopping cart is working good in FF & IE.
