Hi everyone,

I'm working on a website for my company and everything was fine until I went to login this morning. Clicking on the Login link now just takes me back to the Home page and a message appears:

A critical error has occurred.
Object Reference not set to an instance of an object.

I've tried changing web.config and default.aspx to cause the server app to recycle. That didn't help.
I've also tried going to the Login page directly via http://www.cci-leadershipstrategies.com/default.aspx?ctl=login as well as http://www.cci-leadershipstrategies.com/Home/tabid/36/ctl/Login/Default.aspx but neither of them works - the result is the same.

The oddest thing about it is that the last time I worked on the site everything was fine, and noone else has logged since then. Then all of a sudden today I get this.

The only thing I can think of is that the News module might be causing this, as it's the only thing that has changed. I had one test news item that was set to expire on the day after I logged in for the last time.

Any help/suggestion would be greatly appreciated.

Thanks,

Emil

More info about the above problem that I neglected to mention:

I have verified (in the DB) that the Login page has not been modified from the default, i.e. in dbo.Portals table the LoginTabId is set to NULL.

Since I was in the DB anyway I just pulled out the log entry from the Event Viewer. Here's the exception stack trace:

Still no success in resolving this and it's happened to a DNN installation that's only 1 week old.

I'm very surprised by the lack of responses. Does noone really know anything about how to fix this? Come on guys, help!  I'm not the only one experiencing this problem.

Thanks!

Jeremy, your problem is the same as mine. Can you tell me which company you are hosting the website with? I'm with Network Solutions. Just trying to see if there's a pattern here.
