At first: thanks for this great plugin! :)
Now the problem:
I built a multisite on localhost with MLS, everything works like a charm, I'm happy with it.
I uploaded the whole thing to a live server and now if I want to link two articles together with MLS, it doesn't save at all. Old ones are working, no new plugin, only the domain has been changed.
It seems to me that everything else (I mean the wordpress itself) is working but I guess MLS maybe also stored somewhere the magic "localhost" word in the database (?).
