Currently, when vb needs to run a sheduled task, it loads image code at the bottom of your forum page. Except it has a php file as the src of the img tag. This causes the php file to run which in turn runs the next scheduled task. This can, depending on the cron to run and the size of the site, cause a browser to seemingly hang until the script is finished running. This happens because this is a syncronous event. Meaning, it's waiting for the page to finish loading the image.

This mod replaces that with an asyncronous AJAX call to the cron script.

The image code has served vb well but with the advent of AJAX type methods there is a cleaner way to do it. That's what this does.

vBCron is run by a simple link to cron.php in an img tag. This link will activate cron and do updates, then output back to the img tags blank.gif. This mod eliminates that, and instead, uses AJAX processing to activate cron.

Notice that it's in a directory called "upload_the_contents_of_this_directory_to_forumhome".

So just upload the contents of that, subdirectories intact, to your forumhome directory.

Where is there any image used when using a cron? Crons are made to run automatic, aren't they?

On my site my vbadvanced is in the root directory and vBulletin is in the /forums directory below that.

in vBulettin Options->Site Name / URL / Contact Details there are two settings. Forum Url and Homepage Url. These must both be set or it will not function on your vba home page if you have it in a different directory.

The reason being is that AJAX (and for good security reasons) does not work on remote sites. It can only access files on the site your visiting. So the path has to be set to the file using /dir/dir/file type structure instead of http://site.ext/dir/dir/file. To accomplish this I had to compare the two settings above in order to change the path to cron.php when on a vba page that is in another directory.

I hope that helps

It's only there if a cron is scheduled to run at time of page load.

In the footer of your page you should see this.

When vb needs to run a task it inserts the image code there. When it does not need to run a task it leaves it blank. This mod elimates that mess and runs the task in the background with an XHR (AJAX) call to the file. Much cleaner.

I should add that just as vb does not insert the image code when there is no task to run. Likewise, this script does nothing, and inserts nothing, not even the link to the javascript file, when there is no task to run.
