Hi Damon,

Can you get the umbraco.config file to generate by right clicking Content ?

What happens if you right click Home and do a full (slow) publish ?

Thanks for the reply. I tried a full publish and after a long wait where the publish screen went blank, it kicked me out of the CMS login and reported the same error as before: Access to the path 'C:\inetpub\siteroot\App_Data\umbraco.config' is denied.

This caused the website to break as before. I checked on the server and the umbraco.config file was unchanged (same timestamp and size as before). Renaming the umbraco.config file - basically running the site without one - removes the access error and allows the website to load, but the problem in the CMS remains. I am wondering if something in the database got written improperly or partially when the original time out occurred. Below is the stack trace from error and a screen of what happened after the full publish. Any additional ideas or help is greatly appreciated.

Hi, I don't know what sort of access you have to the server, but check the file system permissions ?

That was it. I should have checked that sooner. From development to production, the App Pool name was changed.. bone-headed.

Thanks very much for your help.
