when that is enabled then the post type is ticked in design -> map to hide. unticking the post type will show the map again.
anyways, I now understand how it works with the listings/multisite etc.
What I want is very much similar to Facebook. facebook is on all kinds of languages+domains, and each language has it’s own customer support. If someone posts something on facebook then it’s not just shown in that country, people all over the world can see your posts. That’s what I’d like to accomplish with listings.
WPML seems to be the only tool that can accomplish something similar, but WPML is just a plugin that creates duplicates of listings. I’m not so sure about how good that is, but creating duplicates means more listings, and more listings means slower site and larger risks of other issues.
Using geodirectory over the network just seems more logical somehow.
Thank you all for responses!
