I think I know the login one, check your machinekey string and make sure it matches the one from the last working web.config. Passwords are encrypted using the values from this string.

We have the same problem on our installations.  I imagine many are. 

Here is my workaround I just discovered.  Make a backup.  Always a good idea before playing Russian Roulette with DNN.

Delete the ENTIRE bin directory.  Upgrade your files by copying over the upgrade files.   Copy & rename release.config to web.config.  Copy your connection strings, machine keys and any other customized settings you may have in your old web.config into the new one.

This should get you running.  You may have modules that won't appear.  Go to your backup and copy the DotNetNuke.Modules.* dll files into your bin directory.

This works for me.

 

 

The real question here is what caused it. I had this problem and your solution worked like a charm. Thing is, I had the problem on a clean install - not an upgrade. I also had the problem about 10 days after initial installation. The only major change is that I added a photo gallery, 2-3 days before the problem.

 

Thinking about it I may have compiled the source and selected to sync the site in the early evening, and the site died overnight sometime.


I'm not sure why a recompile of a site that has had nothing changed besied the default skins would cause this sort of problem. I am also remembering seeing a lot of files with a "pdb" extension or some such thing in the bin directory and wasn't sure what those were.

Like you said check the machinekey...if it is still giving you a problem, make sure your "ApplicationName" is set correctly.  That one got me.  It is defaulted to "DotNetNuke", but I changed it on my first install and didn't know that it uses that for encryption also.

<add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="SiteSqlServer" enablePasswordRetrieval="true" enablePasswordReset="true" requiresQuestionAndAnswer="false" minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="0" requiresUniqueEmail="false" passwordFormat="Encrypted" applicationName="DotNetNuke" description="Stores and retrieves membership data from the local Microsoft SQL Server database" />

If you change that on your first install then make sure you make it the same.  That isn't in any DNN instructions and that gave me SUCH a problem in my last upgrade.
