My feedburner account has a different URI

You can change the URL yourself. Go to Administer > Site Configuration > FeedBurner, and in the "Advanced" section, you can set the MyBrand URL to "feeds2.feedburner.com"

Hi
I have done and the system tell me

    * warning: fread(): SSL: fatal protocol error in /var/www/vhosts/stefanovitali.info/httpdocs/includes/common.inc on line 501.
    * The MyBrand domain feeds2.feedburner.com failed verification. Make sure you have edited the domain's CNAME settings before enabling this option.

The feed is ok but i show this and another question:
why a double settings page for this module? I got some (very very few, onestly) problem to find the other settings page. Better one centralized, don't you think?
Anyvay, is just a suggestion: lot of thanks for the module :-)

You can ignore that error. I had that in before Google switched all their domains. *grr*

There is only one *settings* page for the FeedBurner module and only one page to actually redirect feeds on your site. I've moved the settings page to a tab on admin/build/feedburner/settings in the 6.x-1.x-dev version so it's a little easier to find, but those two separate tasks should still remain separate from each other.

I have changed the to http://feeds2.feedburner.com as you mention in #1 but it shows a verification failed message!!!

The verification fails, but it still saves the new URL. I'll work on making that verification less red-errory and more flexible (it was written before FeedBurner moved to Google).
