I could be wrong but this certainly looks like missing AJAX, I'm not sure if it comes with .NET 3.5 SP1 or not... otherwise it's a download you need to install.

You might try making sure your site is running 3.5 in IIS, and upgrading DNN to run with .NET 3.5 in Host Settings. Also see if you can find a script somewhere that tests for AJAX. The new DNN 5 dashboard might be of help if you can get that running.

Remember to always back up your application!

Hi,

Got it working, but not entirely sure why :-(

1) Copy the new version on top again, make sure all files copy ok.

2) I had problems that related to file permissions in the DNN folder. I reser the permissions so that the NT User Acount used by IIS had the appropriate permissions and my problems disappeared after a reboot.

Not sure what happened, but I suspect the initial DNN install set up permissions, but some new files delivered as part of the upgrade didn't inherit the correct (read) permissions. Anyway, after this it all worked ok.

After checking the permissions I also changed the skins back and forth in an attempt to force a cache update.

3) Clear out you local browser cache.

Hope this assists.

Peter
