Hi Boby

Maybe this will not help at all, but could you try to republish the entire site? You know, right-clicking the Content-node in the Content-section, and choose the Republish entire site-option.

Thanks Kim, I had tried that earlier, but didn't help.

No errors logged in umbracolog. The debug messages show that the republishing completes successfully.

Ah wait, the log actually shows this error:

Found the problem. Turns out that this was a permissions issue - Network Service (or whichever user umbraco application is running as) was lacking modify previlage on %windir%\Temp folder (C:\WINDOWS\TEMP\ in my case)

Thanks Kim for pointing me in the right direction. Much appreciated.

P.S - can someone mark this post as solved, as I'm unable to thus mark my own post.

You are welcome. I had the same problem in one of my earlier projects, so I thought that it could be something lika that. Glad you figuered it out :)
