Some help needed with rss-feed and scheduled task

[AfterWorldForum]

Hey,

I'm hoping someone could help me obtain a little bit less noobishness in the more NOT out of the box stuff for vB.

First of all, I'm trying to create a new RSS feed post.

The URL for the rss ishere: http://afterworld.ru/rss.xml

That works fine in the browser and an XML validator also couldn't find anything wrong with it, but apparently vB decided there's a mismatched tag on line 5. I googled, but did not really find anything helpful, so I figured I'd give it a shot here.


Then I also have a problem with a scheduled task I tried setting up. I followed instructions I found somewhere, and created my php file in notepad, added a simple SQL UPDATE query as the only task to perform, and dumped it in the /includes/cron folder.

The code for the page is really simple:

<?php
/*======================================================================*\
|| #################################################################### ||
|| # Update signature posts for users who added their signatures later  ||
|| #################################################################### ||
\*======================================================================*/

// ---------------------------------------------------
// Start Set PHP Environment
// ---------------------------------------------------

error_reporting(E_ALL & ~E_NOTICE);
if (!is_object($vbulletin->db))
{
    exit;
}

// ---------------------------------------------------
// Start Cronjob
// --------------------------------------------------- 
global $vbulletin;
$vbulletin->db->query("UPDATE post SET showsignature = 1");


// ---------------------------------------------------
// Log action
// --------------------------------------------------- 

log_cron_action('Signature posts have been updated', $nextitem);  

// ---------------------------------------------------
// End Cronjob
// ---------------------------------------------------

?>

I tried running it manually, and it seems to run fine, but nothing shows in my logfile. Is that because it actually did not manage to find any posts to update, maybe? (I just did run the statement manually).

Thanks in advance for any pointers.

Regards,

Peter
