I recently upgraded to dnn 5.1.4. But now I'm experiencing some problems at login. Right after a user logs on, I see an error in my eventviewer. The error has someting to do with redirecting to the prefered locale, I guess, but I don't know why... Can anyone helpe me ?
Thanks !
Bart

Source:

I used the install with the wizard. After that, I modified the membershipprovider because we use another database to store our users.

It seams to be solved now.
As I said, I made a custom membershipprovider. In my code, I didn't properly filled the property "preferredLocale" in the userprofile. Now I did, and didn't receive the error...
Thanks anyway for your help

Cheers
