Hi paolo,
You have my permission to get this working. If you have to add test events or posts to your account on my website, please do it. I could only imagine that if you have a BuddyPress integration addon, that this addon would allow connection to a users profile network wide, since BuddyPress is a Multisite plugin. All of the other things you do as a user within my Multisite Network is connected, but not your plugin for some reason.
FYI, I am not trying to use your plugins on more than one subdomain, but I am trying to get the things a users posts within the directory to show up on their profile. Such as, if the user creates an event or creates a listing or new post, these elements should be added to the network account, and when the user clicks on these items within their profile it should take them to the subdomain where the GeoDirectory plugins are being used.
Please advise….
