[Typo3] suddenly no thumbs, no graphics??

[Albert (Pod-Dubon)]

Hi list

 

Don't know what happened but suddenly in the backend no thumbs are generated
anymore for graphs i just added. For the ones I put in yesterday everything
oke.

Also in the frontend the graphics (GIF and JPG) are suddenly not displayed
for the one I add now to the pages I am generating now. The ones of
yesterday are just fine.

I am not aware of any change made in the last hours to any setup or so.
