This product combination does not exist

[peltiertech]

I have had a number of customers report that the Add to Cart button leads to a message saying that "This product combination does not exist". Most have reported that the item was added without this message after a few tries. Other customers make their purchases with no such warning.

I searched the forum before posting this, and I see that the problem can be caused by an updated product ID which was not changed in the button code. But I updated the code after renaming the product. Since the problem goes away for some customers, and others never encounter it, I don't think it's my buttons.

The page with the buttons is: https://peltiertech.com/charts-for-excel/

The button codes in your page currently look and work fine in every browser I've tested, even Internet Explorer.

If you recently changed that product's Item Number and updated the button code in your sales page accordingly, some buyers might still have a copy of the old page cached in their browser, so you can advise them to clear their cache, or force-reload the page to bypass the cache by holding the Ctrl key (on PC) or Shift key (on Mac) while they click the Reload icon.

If that still doesn't resolve the issue for them, please ask them which type of device and browser app they're using, so we can try to reproduce the problem in that environment.

Thanks for checking. I don't think anyone eventually couldn't get through, so it's just been an inconvenience.

Those links all worked for me (a common programmer statement). I had changed the product ID, but nobody should have seen the old links, because I changed them yesterday, and the page went live today.

I told people it was because of all the Cyber Monday traffic. That may or may not be the case, and it's something you guys might want to check.
