I want to change the slug "stadium" to another, lets say "place" so the permalink should be .../place/alliance-arena.

Hello,

See screenshot below.

so simple!! i didn't think that. i was trying to change it from class-anwpfl-options.php !! you are the best. i will buy the premium version now just because you answered me so quickly. Support is very important. I had the freee version few days now and tring to fit to my need. The stadium slug was the last. Thanks again
