I had this problem when I upgrade my project (other .NET Framework version). I used to copy my web.config (a file with my Connection strings, app settings, etc) then I had this trouble.

I solved using the web.config that I had after the .NET Framework upgrade and set the settings in this latest file.

Not exactly adding anything new but at least have the decency to explain what the difference is between the two files (like the target .net version or assembly version or whatever)

Exactly you are right. You didn't add Nothing. It happens a long time ago. Sorry I didn't remember the .NET version or the tags that changed. This is just a tip about how I solved this problem. Have a nice day.

You've said that you don't "remember the .NET version or the tags that changed" - I strongly advise you to get familiar with the concepts of backups and version control - then you would just need to do a file compare to determine what had changed
