I've encountered a major issue on three managed sites. This past week, I updated to VirtueMart version 4.6.0 11214.
The update went well until I saw users having trouble completing their orders. I ran a test, and the problem is that the error message "Invalid Token, in view=cart task=updatecart" appears. It's not possible to proceed with the order.
Regards
Joomla! 5.4.0
PHP version 8.4.5
I've now solved the problem by reloading VirtueMart 4.4.10 11120
Let me know if the problem is resolved in version 4.6.0.
