Hi!
Few days ago one applicant for AdSense reported they can't apply with HubPages, because of "Cannot connect to the server. Please check your Internet connection and try again" error:
Adsense submitting error - cannot connect to server
HubPages support is trying to help:
And in the meantime, there are two more reports:
poppyseeddog - "I have the same problem. Any luck anyone?"
I know this forum is for hosts, not for clients, but is there any chance you could check this signup flow implementation and see if there is anything you could do from your side?
Thanks!
