I put it in custom dir.
SettingsUI.php is in the normal botfolder\modules
06_Settings.php is in the botfolder\main
only custom php's like YG.php or modified php's(whois.php in german) need to put in the custom folders if there is an update 6.9 you don't overwrite your mods
You only have to : "/tell BOTNAME !set" or "/tell BOTNAME !settings" and than the bot tell you 3-4 scripts/links, inside the scripts/links is the "!set MOD" link-list ...this is for me the easiest way to find the right settings for each mod...
But you have to be a SUPERADMIN or the OWNER for the most settings ... I think for the gratz-mod you have to be the owner... but I don't know it exactly
If this doesn't work it could be better to copy the log to the community ...perhaps it is brocken something more
I'm no Bebot-hero or PHP-pro all this is so, how can I help you without more info ...
