Difficult to help if on local, but check for JavaScript conflicts:   http://forum.virtuemart.net/index.php?topic=119638.0

Also if you have selected to use PayPal Express as a pay option the deselect/unpublish it. I have found it to be problematic on locahost.

Thanks for your suggestion. I had already tried to clear Ajax for OPC on the configuration and cart worked. after I selected again
AJAX for OPC and cleared payment method with PayPal, the cart worked.Probabily as you say there was a conflict between libraries
javascript. Now, selecting ajax for OPC and the method of payment with PayPal, the cart works. I hope that the problem will not go back.
Thanks for the suggestion.
regards!

I am also getting "error updating cart" but only when using Paypal Express in combination with the Ajax for OPC setting in VM, using Joomla 3.4.6 and VM 3.0.12. I suppose it is template issue / jquery conflict - perhaps caused by bootstrap, but I can't seem to find the reason exactly. I have made my template from scratch, as leight weight as I possibly can, and I try to use as few "fancy" modules & plugins as possible. So there's not much for me to disable while troubleshooting . As far as I know, my template does not load any other .js files than the ones coming with Joomla 3...

This is the error message in my console :

XMLHttpRequest cannot load https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-6L7031724Y667453Y. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.crashdiet.org' is therefore not allowed access.

When disabling Ajax in OPC it works as it should. Every other payment module, including the classic Paypal checkout, works fine too. But I would obviously prefer to be able to use Ajax in combination with Paypal Express .

Here's how to reproduce this on my test store :

Go to http://www.crashdiet.org/vm/test-categoru/bundle-beanie-scarf-1399-detail.html and add this product to cart, then view cart and try selecting the Paypal payment method. This will show "error updating cart".

I would TRULY appreciate if anybody could give me some hints here . Thank you in advance!

Best wishes

is this also the case when not using the sandbox?

[loppan]

is this also the case when not using the sandbox?

Good point, but yes, sadly it is. Same error message, just a different URL :

XMLHttpRequest cannot load https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-0JE36056D8115024G. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.crashdiet.org' is therefore not allowed access.

But note that checkout still works, kind of... after receiving the message, the "Confirm Checkout" button in VM turns grey - but if I refresh the page I get redirected to Paypal and can pay without problems. Also, if I click the "Checkout with Paypal"-button that appear on my checkout page after enabling Paypal Express, I'm redirected to Paypal without problems. So at least that part works. Still, I can't present such a messy checkout page to the customer of course .

Have never used Paypal express so can't give any definite help apart from Google

they discuss setting the header specifically  .. e.g. $this->response->setHeader('Access-Control-Allow-Origin', '*');

Is there somewhere in the Paypal plug that this could be done?

[loppan]

Hey there and thanks for your time as always!

I suppose this can be done somewhere in the plugin, but isn't it possible that this is some kind of javascript conflict or similiar? I don't get this message when I disable ajax in OPC. I have googled a lot but some people mentioned some security concerns when setting the header like that... which also make me hesitate a little bit . and it would be nice to not have to mess with the code, obviously. At least until we know for sure that this isn't a template issue .

I don't get this message when I disable ajax in OPC

I assume because the call is AJAX when enabled?  Have u studied the calls in the console and compared the 2 situations?

[loppan]

Hmm, this is even more weird.

I disabled ajax OPC, and now, once I select the "Paypal Express" option and click "Save", I'm immediately transfered to Paypal. Even without agreeing on TOS, and without a change to add order comments (unless the customer does this BEFORE chosing payment method, which is unlikely to happen... since the order comments field is below payment method ). On every other payment method I offer, the customer have to click "Save" first, and then "Confirm checkout", which makes sense.

Anyways, I did not encounter any error messages in my console with ajax disabled.

I have the bronze VM membership so perhaps I'll open a support ticket about this, as I'm really getting clueless here now .

Did you find a solution for this?

[loppan]

hi depika, sadly no :/. I disabled Paypal Express and are using the paypal standard thing instead... In the end, I'm fine with this "solution" .

[jimijot]

I confirm the problem still exists.
tested on php 5.6.10, php 7.0.7
Virtuemart 3.0.16, 3.0.17
Joomla 3.5.1
Template without additional scripts except FB/G+
option Ajax for OPC - on
While displaying "Error displaying cart" console displays the following log entry:

XMLHttpRequest cannot load https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-XXXXXXXXXXXXXXXXX. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.mydomain.pl' is therefore not allowed access.

It seems to be interaction between script dynupdate.js and paypal payment plugin.
