Just because on my "high" (hope so) secure server (some improvements and restrictions like safemode) I'm unable to install your version 'safemode' he make a message error like this :
YaBB SE Safe Mode Installer
Error: No Database Selected
(on step 7 to create the user)
also when I make the user manualy I get this error on the index :
An Error Has Occurred!
2: mysql_fetch_array(): supplied argument is not a valid MySQL result resource
(/users/forum/yabbse/Sources/Subs.php ln 186)
Also why every of version of YaBB SE need to automaticaly replace the http user & group & chmods (on an unsecure way) ?
I really like the design and the functions of YaBB but they are some things stranges I see

The current open beta isn't yet ported to safemode (also why to make two different versions one normal and one safemode ? All other BB concurent don't need this and run perfectly in normal&safemode with the same code like phpbb/vb &co)
So if a devel have 2sec to look what's wrong with the security part of YaBB & compatibility in safemode (I tested 4 boards on the same server, phpbb run, vbulletin run, phorum run, YaBB failed (noarmal&safemode version) so it can't be the server) it will be glad because I'll really would like to use YaBB and no other BB

Thanks for support
(ps : why do you need to make system calls to use /var for example, think that if the httpd is chrooted in a jail you can't use this

)
