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.

             border_color=""
             stream="false"
             header="false">
</fb:like-box>

Any help will be greatly appreciated. Thank you. Jack

This extra step for the user will occur occasionally based on Facebook's spam detection system if something causes their engine to think you may be involved in spam or click jacking. A Facebook moderator has confirmed this in this post on their developer forum. Your page seems to only have one like it must be some kind of false positive occurring - or perhaps you have liked and unliked the page in testing too many times.
