What Everybody Ought to Know About Script on RSS Feed

JohnChow has said that need regularly check our feed to make sure there is no broken link, where I was not aware at that time. Until couple days ago, I found my feed cannot work!.

The error message appear when I clicked the feed like below :

The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.
——————————————————————————–
Only one top level element is allowed in an XML document. Error processing resource ‘http://feeds.feedburner.com/SearchEngi…
<meta>

After checked with the RSS feed support, they gave me explanation that “You can’t use scripts of any kind in feeds, especially outside of your item post content; they’re not valid content”.
I remember had installed web analytic script on my index file, where I shouldn’t do that. In Wordpress, you can install the script in sidebar.php or other file instead of index file.

I hope my experience is useful for all of you and as JohnChow said you need to check the RSS Feed regularly.
