I should say that the new events are saved to the mysql backend but 
there is no way to select the calendar to see them as the calendar 
selector pulldown menu is not displayed on the web page.

Same issue as bug 3538.

Other prefs for kronolith are save to mysql.



mysql> select pref_name, pref_value from horde_prefs where pref_uid = 
"p999002@pop3.polymtl.ca" and pref_scope = "kronolith" order by 
pref_name;

But what matters is whether or not the preferences backend is storing 
preferences correctly. kronolith/lib/base.php automatically sets the 
display_cals preference if there are no calendars in it.

prefs.php for both versions are straight copies of prefs.php.dist

The conditions under which  to display the calendar selector in 
template/menu.inc has changed from kronolith 2.0.3 to kronolith 2.0.4. 
I can see the calendar selector in 2.0.3 but not in 2.0.4

The display_cals pref is set to 'a:0:{}' for new users and I can't 
find where to select a calendar. If I replace the pref by 
'a:1:{i:0;s:23:"p999002@pop3.polymtl.ca";}' it works.

kronolith/config/prefs:

// store the calendars to diplay

$_prefs['display_cals'] = array(

     'value' => 'a:0:{}',

     'locked' => false,

     'shared' => false,

     'type' => 'implicit'

);

I believe in version 2.0.3 you could select the calendar.
