my system is:
joomla 1.5.0
jcalpro v1.6.176_beta non_upgraded
PHP Version 4.3.10-22
default theme
system language:
russianstandart joomla sef is ON
i got several problem and i made some fixes.
1. All of month's names were written unreadable. solution was to use:
,'locale' => array('
ru_RU.UTF-8','ru','russian')
,'charset' =>
'UTF-8' in language file 'russian.php'
2. after modifying the event, the USERNAME field in database became empty (NULL)
solution is to add few rows in the admin_events.php:
~row 810: $record->username = $cur_user->username;
~row 781: recur_until = '$recur_until',
~row 759: $cur_user = $mainframe->getUser();
~row 462: ,$mainframe
[because of that, it was impossible to view all modified events from CB_PLUGIN tab in community builder]
3. With SEF turned on, i got wrong links problem (add,edit,delete events) in frontend after clicking on a link in CB_PLUGIN tab link (MY EVENTS).
solution:
in the file config.inc.php, row 96 i changed to
$CONFIG_EXT['calendar_calling_page'] = "index.php?option=" . $option; //. $Itemid_Querystring;
4. Button 'Back' incide the event don't want to work. i decided to leave it untouched, but still..
