Facebook Like Box "Verification Required" Problem

I have searched but cannot find the answer to a frustrating problem of mine. I have embedded a like box on my website. It works well in chrome; however, when I click "like" on it using Firefox & IE browsers, it says "verification required". When I click this, a pop up window appears that also says "verification required"; clicking this brings up another pop up and so on. There's no way to verify. It would be great if there was a way to avoid having my customers verify at all.

<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script>
<fb:like-box href="http://www.facebook.com/pages/Errandly/170685252991884"
             width="155"
             show_faces=开发者_如何转开发"true"
             border_color=""
             stream="false"
             header="false">
</fb:like-box>

Any help will be greatly appreciated. Thank you. Jack
