[TYPO3] Problem with PHP5.2.6 and TYPO3 4.1.6?

[Daniel Bruessler]

Hello,

Since the provider of a site has upgraded to PHP 5.2.6 (on Debian) and I 
have upgraded TYPO3 to 4.1.6 saving in the BE doesn't work anymore. 
Example: when I edit the title of a text and click the save-button the 
page reloads and the change is lost. And I cannot close the document.

I can switch the workspace and have this change when I log in on another 
operating-system and other browser. I just have the LIVE-workspace and 
the draft-workspace - with default settings. Also there no saving 
possible. (and shure - all caches are cleared :-)

#Any idea what causes this?

Cheers!
Daniel
