Running into a maddening situation that we haven't been able to track down. On our site, www.oldpatterns.com, some customers report that they can't see any items in their shopping carts. In some cases, switching browsers fixes the problem.
Personally, if I use Chrome or Firefox on certain macs, I see the following behavior, but everything seems to be OK if I switch to incognito mode or use Safari:
1. Log In
2. Add an arbitrary item to my shopping cart
3. Click on the "shopping cart" button
4. Get a message saying "Your Shopping Cart is Empty"
Sometimes, I also notice that the "Log Out" button has changed to "Log In", but not always. If not, I can use "checkout" to check out and my order appears to be correct. If it has changed to "Log Out," I don't get the checkout option. If I switch to incognito mode and log in, or log in via Safari, I can see my shopping cart.
Refreshing the page and clearing the cache does not seem to help. Turning off extensions in Chrome did not help, either.
We're running PHP 7.4.16. We tried updating to a newer version, but saw other problems with the site. I haven't found any Zen Cart log files that seem to correspond to the issue, though I am not a PHP expert.
Thanks in advance!
