Your Manual page does not contain content...!?

I tried now php error_reporting:

Fatal error: Call to undefined function mb_convert_encoding in /var/www/mediawiki-1.24.1/includes/HtmlFormatter.php on line 66

I think I know the problem. I need mbstring on my Apache.

From the extension start page: "Although MediaWiki doesn't require it, PHP must have mbstring support for this extension to work (Task T62174)."

I call our Network admin and ask to install it... Hope that it will solve the problem.
