Error 'Root element is missing' when trying to 'save and publish'

General

Hi, I'm totally new to Umbraco and am getting the below error when I try to 'save and publish' any page. I'm not aware of anything being modified which might have caused the problem however can confirm that this is a recent issue. It would be great if someone could point me in the right direction please!

We're running:

1. Umbraco v 4.7.0 (Assembly version: 1.0.4090.38017).

2. Windows server 2008 SP2

3. Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1022

Thanks,

Marios

Hello,

You could try to delete the ExamineIndexes folder which is in \App_Data\TEMP. You might need to stop your website in IIS first before you can do this.

After that you can start the website again and the ExamineIndexes should rebuild itself. Than it might work again.

Amazing! You're a superstar Jeroen!

I deleted the folder and then restarted the website as suggested. It took a couple of attempts to 'save and publish' the page I guess because the index files were being re-created but I can now publish pages again!

Thanks again Jeroen!
