I found it...
FYI
Code:
cd /usr/local/cpanel/base/horde/config
pico prefs.php
ctrl+w ( search for // UI theme )
you should see the following:
// UI theme
$_prefs['theme'] = array(
'value' => 'mozilla',
'locked' => false,
'shared' => true,
'type' => 'select',
'desc' => _("Select your color scheme.")
);
Change the underlined part to whichever theme you want:
/usr/local/cpanel/base/horde/themes
azur
barbie
bluemoon
bluewhite
brown
burntorange
camouflage
cornflower
gennevilliers
graphics
green
grey
kolab
lavander
lightblue
luc
lucblue
mobile
mozilla
NeXTgrey
postnuke
print
purple
simplex
Will this change be overwirtten the next time horde gets updated? Most likely
Should this be an option in cpanl for each domain? I think so
Should WHM have a global default option? I think so
