Thread:Extension talk:S5SlideShow/Fatal error with Mediawiki 1.21.1

Hi,

in Mediawiki 1.21.1 I got the following error which I managed to fix according to

Fatal error: Call to undefined function wfLoadExtensionMessages in C:\inetpub\mediawiki\extensions\S5SlideShow\S5SlideShow.php on line 123

For the fix remove (comment) the line wfLoadExtensionMessages('UserMagic'); in S5SlideShow.php

Works for me! Best regards, Max
