Hi,

I just installed Dotnetnuke 4.7 in two steps. Forst 4.3, then an upgrade. Reason, my provider supplied the 4.3 version in install, then i had to upgrade to 4.7. Once upgraded i get the following error:

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error:

I have no clue where to look since the message is not very clear about the real problem.

Thanks and regards,

Jerry

I thought file permissions were set by the installation and upgrade process. Didn't set them explicitly.

I had to do a lot of the installation twice with rewritten scripts since i have troubles with the case-sensitivity issue which is spoken of in some of the other threads. Could this be it?
