I am getting issue with verify domain

I am getting the same error...

I am seeing this in the rendered source for the "Verify Domain" button:
 

<button type="button" class="bossSetupBtn" onclick="self.parent.location.href='';">Verify Domain</button>

I was having the same problem. It has been this way for at least a couple weeks (I can't believe they haven't fixed it). There is, however, a workaround. Log in and go to https://developer.apps.yahoo.com/manage. That page lists all your domains with working verify buttons.

I have the same error.... that's too ridiculous!!!!
