Check that your Connection Profile settings are as described below.

To publish to AOL's server, you need to enter the following settings in the Connection Profile screen:

Hostname or IP address:
User identifier: anonymous
User password:
Initial remote folder: /screenname
WWW site address:

With all the above settings, replace "screenname" with your AOL screen name.

Also, please ensure that your screen name is rated that of an adult, as opposed to a child, or you will not be able to publish your site.
