Can't login my previous FTP accounts after installing this script

After installing script I can't use the previously used FTP Accounts.

And it is very hard to install the script because in most cases I got this error when I try to apply settings:
2021-04-21 20:55:39,198 s1.gmgaming.hu proftpd[28621]: mod_ctrls/0.9.5: error: unable to bind to local socket: Address already in use
2021-04-21 20:55:39,217 s1.gmgaming.hu proftpd[28621]: fatal: AuthOrder: AuthOrder has already been configured on line 89 of '/etc/proftpd/proftpd.conf'

With the new GameAP created user, I can't modify the server files because of permission problems.

Solved like this:

find /srv/gameap/servers -type d -exec chmod 775 {} ;
