I'm having a really unusual problem on new site.  I created it as a child portal and created all the content without any problem.  I then pointed the real URL to the acutal site and then the problems began.  The problem occurs when I go to site www.rbownerstoday.com, but use url rbownerstoday.com.  Note that the "WWW" is missing in the second url.  When I go to rbownerstoday.com and click on either login or registration, we get the expception below.  This occurs with login in the default configuration for login and with a seperate Login Page.

Does anyone know what is wrong?

I found a way to make my problem go away, but I'm not sure it was a fix.

Initially, I created this portal as child portal.  So it was at www.abc.com/rb.  I then added the portal alias rbownerstoday.com which is the real portal URL. 

I then (using MS SQL Manager), manually deleted the child portal alias from the portals alias list.   Now the problem has gone away.  Don't have a clue as to why this fixed it.   Note, I had to use MS SQL Manager to delete the child portal alias because DNN will not let you delete the child portal alias that the portal was created with.
