[TYPO3-ttnews] Temporary DB Mount in Page Browser

[Nicolai Schirawski]

Hi list,
 
after update to news version 2.2.0 (running on Typo3 4.5 LTS), the page tree browser behaves strangely.
If I click on the backend-modul web->news the page-browser shows typo3-logo and name of the site in the first line, in the second line "root" with a clickable red cross in front. If I click this, I get a "temporary DB mount, path /root/"
 
This is strange, because on another Installation (also news 2.2.0 on typo3 4.5), the news-Module behaves exactly as the other modules eg. web->page
 
Any idea?
 
Thanks
Nicolai
