Trying to add a Text Search feature to my website and after I add in the search box etc and publish it.... when I try to test it a pop-up asking for username and password appears just like when you 1st publish.  I have had other sites where I have added a search box and this didn't happen  Why and how do I fix this.

yes, FP Extensions ARE installed

Here's the URL of my problem page  http://kingdomrecordings.com/search.htm

In Google I found one article that suggests that a username and password might be requested if you have used hotlink protection for your site graphics or if any graphics are stored in password protected folders.
