Hi again to every one,
Note please: I have just updated to 6.2 version.
I added a piece of code that strangely with all the passages and was lost and that allowed to recover the cities created with Apixu.
I also added the "Palestine" state which a user sent me via a function which I introduced in the add-on and which signals unregistered states.

@Joseph, I tested it withnvdapy37-20190228, it's ok.
p.s.
I am about to leave and I come back Monday.

Regards
Adriano
