Thread:Project:Support desk/A question to 1.21.6

Hello,

I updated www.mobadaten.info from 1.21.5 to 1.21.6 this minute.

Is it correct, that all the bundled extensions in 1.21.6 are different to those in 1.21.5? Because after the the change to 1.21.6 the simple search function is deactivated although $wgVectorUseSimpleSearch is set to true in LocalSettings.php. The collapsible functions on the sidebar are not available. And the special page for the interwiki data throws an error:

[1df3adb9] 2014-02-28 21:49:40: Fatal exception of type MWException

Many thanks in advance for an answer.
