Hello,
There is a litlle bug in Monthly Calendar Popup : previous and next month (at each side of months select list) are always displayed in english. My phpscheduleit is french so it is a little strange, cause months are in french in the select list. I corrected this little bug with the following :
* in lib/Calendar.class.php
line 209
<?= "< " . strftime("%b",mktime(0,0,0,$prevMonth,1,$prevYear)) ?>
becomes
<?= "< " . substr($months_full[date('n',mktime(0,0,0,$prevMonth,1,$prevYear))-1],0,3) ?>
ligne 225
<?= strftime("%b",mktime(0,0,0,$nextMonth,1,$nextYear)) . " >" ?>
becomes
<?= substr($months_full[date('n',mktime(0,0,0,$nextMonth,1,$nextYear))-1],0,3) . " >" ?>
