I installed populus on the sub domain:
al.albpetrol.net
and than I copied the whole "al" and I placed it on my new sub domain:
en.albpetrol.net
I copied database from the first site and I dumped it in the second's site new database.
I did all changes on the configuration.php file to suit the new path.
Can someone help what i have done wrogn for the new site to act like the old one. That is why I created 2 exact pages in 2 different sub domain because I want them to work separately from each other
