Hi, I can login on my website fine in Firefox but not in IE8. Clicking on the Login link takes me to the Login facility and I get to enter my User name & Password but when I click the Login button, the system simply returns me to the page which I last viewed. Can anyone suggest anything?

It probably is a javascript error.

Have you tried switching your browser to IE7 compatibility mode? What happens there?

In IE8, type F12 to turn on developer tools and then start script debugging. Are any error reported?

Thanks for that. Running in IE7 compatibility doesn't fix it. I turned on Script Debugging and can't see any errors but I'm not familiar with this so I may be missing something.  Perhaps someone could have a quick look? I have set up a user ID as: guest with password: 1234abcd. If you get to an Access Denied message, it's working. If you are returned to the page from which you left, it's not working. I appreciate any help on this.

thanks for the post guys! really helped a lot.

I installed DNN locally on win7 and was testing using localhost and my PC name from other computers on my network. Login worked fine from IE locally (localhost) but did not work as described above from other PCs using IE(8) - it accepted the userID and PWD but then returned to the home page w/o showing the user logged in. I read this post and tried using Firefox and it worked fine. Weird. Does anyone know the cause of this behavior?

Check to make sure that javascript is enabled in IE. Also, you could check to see if there are any javascript errors. That is the usual problem. That is works with Firefox does seem to indicate an IE error, not a DotNetNuke error.

If your localhost website containes a "_" e.g. website_test, IE does not allow the necessary cookies to write to the application (DNN).

change your testing website to be one word and test - it worked for me.

Hi guys..thanks for the information posted...such a great help. Keep it up!

Dotnetnuke version 07.00.04. I can confirm the above information is correct. I had a local DNN web site on my laptop with a portal using a domain http://mwd2013_test which refused to sucessfully login me in with IE7 after entering the credentials (worked okay in Safari). Changing the url to http://mwd2013test fixed the problem. Many thanks for posting the solution.

Thanks Bets!
I had the same problem and it turned out to be because I had a '_' in my site name. I blew the instance away, created a new one without the '_' and I was able to log in.

Thanks guys!
