FOP not working

I can open the FOP by going to http://ipaddress/panel just fine, but if i try to open the FOP through freepbx it gives me this error:

Couldn’t load
variables ADMINS.txt?aldope=94189

I tried the solution that was documented here:

But when i did that, opening the FOP from the freepbx link would only load the characters “00” in the top left of the iframe. Can some one point me in the right direction?
