Hi all,

Getting weird upgrade issues - I've seen this many times however I can never remember what on earth it is I do that gets the thing working again...

Basically take a working portal (seemingly of any version of DNN) and perform the upgrade - you know the drill backup web.config and database and merge custom information into new config file.

Run the web-site and it says the database upgrade is successful.

Click the link to access your portal and nothing happens - actually that isn't strictly true - something happens - it says "Page cannot be displayed."

The issue is very strange in that no breakpoints set in Default.aspx are ever hit. Only the app_start in global.asax causes the debugger to stop...

Has anyone else seen this?

So far I've checked (and double-checked) folder/file security permissions.

I've tried enabling impersonation.

I'm sure that the last time this happened I simply switched from using the VS2005 web server to using IIS and that helped (it actually gave me a different set of errors but these were easier to fix).

About to try removing all web-project references and adding them back again - just in case...

All other suggestions warmly received!

Ade
