Hello, I see that you can! But I can't! I don't know the reason! Have you some idea about that? Can be a problem of hosting cache or something like this?
See on edit details the real names of web-domain and web-subdomain. We have two webs now. In a main web-domain https://www.webdomain.com it runs with Stora and is not possible manage the languages in product images on the back end. I tried again and it not runs for me.
You can find it in Administration --> Virtuemart --> Product --> Product images.
In the other web put in a web-subdomain https://www.webdomain.com/subdomain it runs with Storebox and they are no problem.
Thanks for your help!
