This is a nightmare !
I have look around everywhere into the tables !
I can't find something hard about it.
I jump into the code where i saw in "tiki-setup.php
$feature_wiki = 'y';
$feature_articles = 'n';
I changed it to
$feature_wiki = 'n';
$feature_articles = 'y';
That doesn't changed a thing and i have seen there a lot of preferences and features i don't use checked to "yes"
Is that file realy usefull ?
