I am attempting to install cldr. In previous installations, I have not had any issues with this extension and is currently live at wiki.seg.org. When working on updating the Mediawiki software from 1.23.2 to 1.26.2, after installing several other extensions, I get this message in the command prompt when attempting to update the database after installing cldr.

PHP Notice:  Use of undefined constant MW_MATH_MATHML - assumed 'MW_MATH_MATHML' in /var/www/html/mediawiki/LocalSettings.php on line 166
PHP Fatal error:  Uncaught exception 'Exception' with message '/var/www/html/mediawiki/extensions/cldr/extension.json does not exist!' in /var/www/html/mediawiki/includes/registration/ExtensionRegistry.php:106

I have enabled the Math extension and set MathML as the rendering option. This is how it appears in LocalSettings.php:

require_once "$IP/extensions/Math/Math.php";
// Set MathML as default rendering option;
$wgDefaultUserOptions['math'] = MW_MATH_MATHML;
$wgMathFullRestbaseURL= 'https://api.formulasearchengine.com/';

Can someone please provide guidance in troubleshooting this issue? Thank you.
