Thread:Project:Support desk/upgrading MediaWiki to Version 1.17.2

Hi,

we are using MediaWiki for 6 years (version 1.8.2) now and currently we run into many problems. So I decided to upgrade to version 1.17.2, I checked all the requirements and also the manual for updating. After the 4th unsuccessful try to update I would need some help, what's currently the problem.

Here some info:

Virtual Windows Server Apache WebServer 2.2.21, PHP             5.2.17, MySQL           5.0.51a, MW              1.8.2

The PHP update command runs 3 seconds and that's it, no errors showing. The only error we find was in the PHP logs [15-Mar-2012 12:26:02] PHP Fatal error: Call to a member function setCacheTime on a non-object in D:\Websrv\Apache2\WebSites\...\wiki\includes\parser\Parser.php on line 4771

Please could you help me in this case

kind regards Mike
