 MathML support:
 If you prefer MathML rather than images you can use LaTeXML to convert the
 math tags to MathML. To use that feature you have to enable LaTeXML by setting
-$wgUseLaTeXML = true;
+$wgMathUseLaTeXML = true;
 It is possible to choose LaTeXML as default option (for anonymous user) by setting
 $wgDefaultUserOptions['math'] = MW_MATH_LATEXML;
 in the LocalSettings.php file.
