I have virtuemart 3.2.4 on Joomla 3.8.1. I don't user payment plugin.
When a user has a cart and is redirect for select shipping method and clic for select method i have erroer message (error updating url). Virtuemart costruct url with selecte dmethod id as suffix so it doesn't exist.
This problem exist only if Ajax For OPC is enable and i don't want disable it because i don't want my user must confirm their command twice.
Have you an idea ?
