Hi @ingeniero

I agree, if two collections are installed in different domains, then they should act as different sites.

I think the crumb error is produced because the site cookie doesn't match the current domain, that's a shared thing that the end user should not know.

The dev team is already informed.

Thanks for reporting.

@ingeniero please check this page: http://b2evolution.net/man/multiple-domains ("Cookies" section). The use case you mentioned is documented in that page.

I found it needs many changes to make it work!
Maybe you developers are not any interested that normal people can contact you
for me the contact is the payload!

After 2 weeks hard work I got it running :)
