Product not adding to cart after latest update

[joozen]

Joomla! 3.10.10
VirtueMart 4.0.6 Eagle owl 10690
PHP 7.4.3

After latest update when you click Add to Cart Virtuemart returns to main page. All was working before update. Please advise.

ps. Just noticed, PayPal express checkout from oniline store stopped work as well. I don't know what been done with product details or ever file but shop actually stopped working.

Rolled back from backup, its working now. Thanks for help.

Anybody know a fix for this? I'm unsure how you go back to the previous version.

you need to report what exactly is wrong or at least provide all info -- versions, live site and example page

[sjstv]

Sorry, thought it would be a common problem as it occurred on the last update.

Joomla 3.10.8
Virtuemart 4.0.6

Try the Buy Now button. https://www.sjstv.co.uk/parts-shop/all-categories/remote-controls/4776/lg-genuine-oem-remote-control-2021-models-mr21ga-akb76036201-detail

I don't have one page checkout on my site. I'm using native checkout. When you try to add product to card it redirect to link yousite/# and redirect to main page. Exactly the same with Paypal Express button on product details page. After I restored site from backup to previous version it work as it should.

Checkout on your restored site uses VP:
<link href="/plugins/system/vponepagecheckout/assets/css/light-checkout.css?ver=7.9" rel="stylesheet" type="text/css" />
   <link href="/plugins/system/vponepagecheckout/assets/css/responsive-procheckout.css?ver=7.9" rel="stylesheet" type="text/css" />

Only way I could get out of it was to do a full restore. Now running VM 4.0.2

You can duplicate this behaviour in product details page with

VirtueMart 4.0.6 10690
Native Checkout
No third party plugins installed

by setting "Display modal popup upon 'Add to cart'" to No

this should take you directly to checkout without the "Add to Cart" modal popup,

but you just remain on the same page.

you can also see this with the standard VM checkout and the "OPC" not selected so you have separate views for shipping and payment selection.
The Save form does nothing..  i.e. u stay on the same view ..

{
   "updatecart": "",
   "virtuemart_shipmentmethod_id": "4",
   "option": "com_virtuemart",
   "view": "cart",
   "task": "updatecart",
   "controller": "cart"
}

doesn't even reach the cart controller afaik .. certainly doesn't reach the function updatecart() ..
assume a router problem but weirdly the almost same post form the ajax (i.e. enable the core OPC setting) works fine!

<link href="/plugins/system/vponepagecheckout/assets/css/light-checkout.css?ver=7.9" rel="stylesheet" type="text/css" />
   <link href="/plugins/system/vponepagecheckout/assets/css/responsive-procheckout.css?ver=7.9" rel="stylesheet" type="text/css" />

If it about my site VP turned off because Online Store PayPal Express not working with it. Therefore I'm using native checkout.

Apparently does the inactivation not enough. VP OPC code is involved in your error.

Thank you. OK Uninstalled. But still a bit scared to update so far all working. Probably I'll try to do fresh backup just before and update it later today. Will see what's happen.

[Jörgen]

Yes backup before update is always a very good idea
