I'm new to vbulletin, so please be gentle with me if I did something stupid here. I installed this exactly as specified, but I hit "run now" for the update invites count" in the scheduled task manager, and got this error:

Warning: Division by zero in /includes/cron/update_invitecounts.php on line 79

It hasn't given any invites out at all. What did I do?

download the hack again and reupload the file update_invitecounts.php

Thanks, but I allready did that twice and got the same error. :disappointed:

Do you have 0 set for number of posts to recieve 1 invite? That would do it.

That would be a really stupid mistake, wouldn't it?

That is exactly what I did. :speechless: Thank you for helping.

Edit, oops, I made sure nothing is set to zero anymore, and I am still getting the same error. Apparently, that wasn't the fix I needed.

works on 3.5.3 ?

i upgrade my testboard to 3.5.3 and mail function is working
but invite mails not working
i donno maybe im too newbie here and need surfing forum more :D

Edit: works fine on 3.5.3

Is no one else having this problem with people getting too many or negative invitations?

Negative invitations are by design :)
As for too many, you need to set up the minimum amount of reputations and/or posts to receive new invitations.

Look man, I do have the settings configured properly. My settings are:

Invite System: Enabled
Registration by Inivites Only: Enabled
Mutual Buddies: Enabled
Image Verification: Enabled
Invite Expiration: 7
Min Posts to recieve changes in invites: 24
Min Reputation to Recieve Invites: -1
Invite Changes on Reputation: 1
Posts required to recieve One invite: 50

Now, people who have more than 24 posts are recieving 7 invites, when they should be recieving zero. This is due to your code, which starts invite_increment at 7 and subtracts 1 for every day inactive. So people that are active every day, yet make no posts or have any reputation changes are recieving 7 invites!!

Also, the user who recieved -11 invites had 3 posts in the last week and had NO reputation changes.

This is obviously not right; I have redownloaded your update_invitecounts.php file and verified that I am using the exact same file...
