I have this running on my 3.6 system (installed under 3.5) with some minor modifications.
line 74 in vbms_new.php:
Code:
if (!empty($_POST['action']))
line 31 in vbms_class_mail_message.php:
Code:
define("VBMS_CRLF", "\n");
and I run the vbms_cron.php as a cron:
Code:
*/1 * * * * /usr/bin/wget -q http://www.mysite.com/forum/includes/cron/vbms_cron.php --delete-after
I'd be glad to pitch in where I could as time permits; our users have used this for some time with no problems and other than these few changes for 3.6, everything seems to be working fine now.
