Modification of permalink
Hello everyone,
i just want to know how to set the permalink such that for an Ad that for instance has been published twice, the number 2 does not appear beside the name in the permalink:
Permalink:
http://www.carpoolingtest.ret./ads/berlin-paris-2/
Because the city paris has been chosen twice in two Ads, the numer 2 appear in the permalink.
Thanks in advance
