You need the shell script to change the working directory to where vBulletin lives.
If you call /usr/bin/php directly from cron, your working directory will be $HOME for the account running cron and cron.php won't find any of the includes it needs.

Thanks, this is a very useful mod :)

It also works on Windows for those of you that have cronw installed.

Does still work with vB 4.

Im Happy! :)

Humm.. Why not adding this to crontab..?

(Needs wget, fetch or similar).

* * * * * /path/to/wget -O /dev/null "http://myforum.com/cron.php" >> /dev/null 2>&1

The image is still fetched, but not stored or displayed - as wget, when invoked with the "-O" option, outputs the data to /dev/null.

It seems to work fine here. :)

Any directions on how to use this add-on? Added the .xml file into vBulletin and scheduled the CRON script in my cPanel but nothing is happening.

anyone tested this with 4.2?

yes..... works fine for me
