Hello, I'm having an urgent issue with my RSS feeds that I use on my site. For some reason the feeds that I have are suddenly not coming on my site. Now I've checked the feeds and made sure that they are still working or if it sees information when I hit the rss feed directly and that's fine. So right now I need someone to look at my code and see if there is something even though the code has not be modified for sometime now. I really need to get his fixed because it stops a lot of stuff to happen on my site:

www.coloradocutthroat.com/index.php

It's cutting off my menus and a whole bunch of stuff
<? 
  # where is the feed located?
  $url = "http://nvgaonline.com/Forums/index.php?act=rssout&id=3";
  # create object to hold data and display output
  $rss_parser = new myRSSParser($url);
  $rawoutput = $rss_parser->getRawOutput();	# returns string containing HTML
  $items = $rawoutput['RSS']['CHANNEL'][0]['ITEM'];
?>
<ul>
<?
	for($i=0; $i<5; $i++) {
?>                
	<li><a href="<?=$items[$i]['LINK']?>" title="<?=strip_tags($items[$i]['TITLE'])?>" target="_blank"><?=strip_tags($items[$i]['TITLE'])?></a></li>
<?
}
?>
</ul>
                <br />
              </div>
              <div id="nvgaNews"><img src="images/coloradoCutthroatConnection_NVGAtheIndustry.gif" alt="" width="241" height="12" /><br />
<br />
<? 
  # where is the feed located?
  $url = "http://nvgaonline.com/Forums/index.php?act=rssout&id=2";
  # create object to hold data and display output
  $rss_parser = new myRSSParser($url);
  $rawoutput = $rss_parser->getRawOutput();	# returns string containing HTML
  $items = $rawoutput['RSS']['CHANNEL'][0]['ITEM'];
?>
<ul>
<?
	for($i=0; $i<4; $i++) {
?>                
	<li><a href="<?=$items[$i]['LINK']?>" title="<?=strip_tags($items[$i]['TITLE'])?>" target="_blank"><?=strip_tags($items[$i]['TITLE'])?></a></li>
<?
}
?>

I'm also getting the following error on some page:

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.

I've made a backup of my code and took out the rss feed out of the index.php section but I want to know what is going on with the feeds

Two things come immediately to mind.  Where is the code for class myRSSParser?  And where is the PHP that generates the home page.  The script is ending prematurely.  Set error reporting to E_ALL and try the home page again.  Standing by, ~Ray

If you run run a WordPress, you understand the potential headaches you may face when updating your plugins and themes. Do you choose to update on the fly and risk taking down your site; or do you set up a staging, keep it in sync with your live site and use that to test updates?

Attached is the code snippet of the file that parsing the RSS feed!! Try it for your self using the code I posted above and let me know if it works for you
<?PHP
