Hi Rosali, and thanks for this plugin.
I have to small (non-blocking) problem, don't know if they are related.
First, my roundcube log warns me with :
roundcube: PHP Warning: in_array() expects parameter 2 to be array, null given in /var/wwws/mail/plugins/calendar/calendar.php on line 1094
the corresponding line is : $enabled = in_array($num, $workdays);
I'v check my config, and workdays seems well defined to me :
$rcmail_config['workdays'] = array(1,2,3,4,5);
Next problem is the use of the "first_hour" parameter. Is this supposed to fix the hour at wich the view of the calendar starts ?
Because my calendar view always start at 00h, and ends at 24h, causing very small cells. I'don't see any effect when changing "first_hour"
I hope I was clear enough, I can provide precisions if needed.
