Check your server error logs. If you don't know where those are, ask your host.

Also take a look at this thread: http://www.vbulletin.com/forum/forum...-errors-on-rss
It's regarding the same SQL error you are receiving.

error log file doesn't contain information regarding rss or external.php. Any particular content i need to search in error log.

Read through this post, it is most likely the issue, http://www.vbulletin.com/forum/forum...5&p=829758
