Hi,
I am working with DotNetNuke 4.0.2, Windows XP Professional (Service Pack 2 - full version). Visual Studio 2005 and SQL Express Edition 2005.
Whenever I create new application with DotNetNuke web application framework, it will work fine and 'Welcome.html' file will be displayed in studio. I will follow all the steps in that file and run the application and my DotNetNuke will be installed successfully. I will click on 'Click here to access your portal' and 'default.aspx' page will be loaded and I can work with it.
The problem is that when I will close the browser as well as studio and then re-open the same website from the studio again and try to run it then I will get the following error in 'default.aspx' page:
DotNetNuke Upgrade Error
The Assembly Version ( [ASSEMBLYVERSION] ) does not match the Database Version ( [DATABASEVERSION] )
ERROR: Could not connect to database.
Cannot open user default database. Login failed. Login failed for user 'ABC\ASPNET'.
Please help me to solve this error.
