Check permission settings on your umbraco folder, as this is mostly the cause of this

Cheers,

Hi. I work on the same project and have been looking into the problem as well

We have checked that. Persmissions are set to full access to "Network service" and files are readable. I can also add that the ajax toolkit is a 1.01* version.

This appears in the umbraco error log:

Thanks Lee. This fixed the problem :)

Ahh. Hit the wrong button, and gave a 1+ instead of the "correct aswer"-button, and now I can't mark this issue as solved.

Hi Kim, if you refresh the page - the "mark as solution" button should reappear. (I think).

Glad your problem is sorted!

Thanks, Lee.

Hi,

I have the exact same problem. Could anyone tell me exactly what permissions to give?

//Kalle

Hi Kalle

What we did to solve this problem was to give the NETWORK SERVICE full access to the "Windows/Temp"-folder. That solved the problem for us back then.

Hi again Kim.

I still have the problem for some of my sites, even tough I have the right permissions on both the umbraco folder and the windows - temp folder.

Do you need to restart the IIS or something?

//Kalle

Also, should the application pool run in integrated or in classic mode?

Well, back then when we had the problem, the site was running on Umbraco 4.0.2.1 with an application pool running in classic mode. Don't know if an iisreset helps anything, but it's worth a shot :)

Hello again,

I still have this problem on my sites. When I do an IIS reset it works for some hours, and then back to not shoeing any nodes!

I have set the full permissions for NETWORK SERVICE to c:\windows\temp and all the required folders in umbraco-folder.

Any ideas?

In the logfiles I get this:
