When clicking "Verify domain", I get a "Domain verification fail" error without any further information. I get the same error message when clicking "Skip verification".
I checked that both url to check and favicon are available from outside my network (Note that due to automatic server settings script, you might find that the domain requires an authorisation from time to time if you try these urls - but that was not the case when i did the tests)
I searched all over the forums, none of the mentioned issues ("yahoo" in application name, unsupported domain, invalid favicon...) seem to apply to my case.
I posted a couple of weeks ago my problem in reply to an existing post, but having got no response I try to create a new topic, hoping to get more attention.
