So you want the public broadcast message to show for a longer/shorter period? There is a simple solution (see How to change the duration of a public broadcast message):
You can increase the time the message will be displayed by editing the following lines in mainfile.php:
$ref_date = $tdate+600; |
and
setcookie("p_msg",$mid,time()+600); |
Adjust the 600 to a value that matches the time you want the message displayed.
