I am not sure that this is the right forum to post this in.

I upgraded to 5.1 from 5.01 and it has been running for a few days now with no problems.  I logged out of my account so I can log in as host.  The logout seems never to have completed.

Ever since this event, whenever I go to the site I get Internet Explorer cannot display the webpage.  I get this from the server itself as well as from remote.  There are no errors that display on the screen.  Nothing on the site seems to work.  I have copied the entire DNN 5.1 install over the installation and I get the same thing.

If I rename Default.aspx I get an error that there is no default page configured and If i take out the password to the DB in the web config I get an error.

Any idea what went wrong? 

I get the same problem.  My site is externally hosted.  I also get the same error page when trying to add new pages.

The web.config is fine for me.  If I rename the web.config file,  I get an actual error.

Some more information.  This has to do with the default page only it seems (example: http://xxx.xxx).  I can go directly to the logon page (example: http://xxx.xxx/Home/tabid/38/ctl/Login/Default.aspx?returnurl=%2fDefault.aspx), it will come up and I can log on.  If I check remember me, I can go to the same link that did not work before, and it works.

It seems to happen wether I am on the lcoal network or outside.  If the user is not logged in, the main page does not come up.  If they are logged in, it comes up fine.  If I send a user the entire URL to the actual logon page, it will work, they can logon and click remember me, and no problems from there.

This happened with DNN 5.1.  I previously had 5.01 and this did not happen.
