Can you see in the log file if it shows any exception? Also, try to clean APS.NET temp files in: [C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files] to re-synchronize content types.

Thanks, I tried deleting the files (and restarting the app pool in IIS), no luck.

The log has the following error which might be related:

Which basically tells me "dojo asked for something in the db that went wrong" :P

I have the option of rolling everything back and restoring the epi database now, so I'm going to try one more time.

Okay I rolled back the db and the code, and commited the upgrade again, and this time it worked. Apparently something went wrong during the build, so I need to check the build messages more closly if something goes wrong when I roll out this code to other systems.

Thanks for your input!
