"error undefined" when trying to add to cart on iPhone

Hi:

I just installed OpenCart and set it up with PayPal. It's working perfectly on my PC, but when I try to "add to cart" any item on my iPhone, it consistently sends up a message saying "error undefined. Close." Does it work on phones?

Thanks
Kenny

I just tried my test OC 3.0.3.6 web site on my iPhone 6 (OS 13.6) and it too put up a window (see screen shot) that said "error undefined".
This is the default OC, no extensions added yet, still running basic tests on conversion.

Test site (which will be up and down at random) is https://www.flippers.com/catalog_oc_3036. Please don't buy anything shown- they do exist on my real store.

It does work fine on my desktop with FireFox 79.0 (Mac OS 10.13.6).

I'd say this is a bug!

Hmm, just tried it again, and it accepted the addition to the shopping cart....annoying! Also added subsequent items. Will close the Safari browser window and try again...
And now I can't get it to fail.
Must be something to do with caching on the iPhone I suspect...

Thank you for your reply khnaz35.
The site url is https://www.onlinepianoteacher.org/keyboards/
However, as I said, "add to cart" works fine on my PC, but not on my iPhone, where instead I get "error undefined," just like the screenshot in the other post.

Thanks again
Kenny

You will run into CORS by directly accessing via www if that's not set in your config..

Try not accessing your site using

https://www.flippers.com/catalog_oc_3036

and try using

https://flippers.com/catalog_oc_3036

You need an .htaccess redirect for www to non www.

or update your config to use www if that's what you prefer, either way you will need a redirect for www or non www.

Thanks very much switch. That was the problem. Now OpenCart's "add to cart" works perfectly on my iPhone as well as it does on my PC.

Thanks again,

Kenny

Other than the possible CORS issues, I noticed from other users experiences that iPhone's Safari browser can be more cumbersome in general. E.g. when developing a theme for OpenCart, make sure to test it separately with an iPhone device, too, in addition to Android, Windows, or Linux devices. Some standard events in iPhone's Safari browser fire up differently, and the Safari autofill function has issues.

Could you expand the "CORS" acronym please? I am not familiar with it.

Thanks!
