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 Stack trace: #0 /var/www/html/mediawiki/includes/GlobalFunctions.php(181): ExtensionRegistry->queue('/var/www/html/m...') #1 /var/www/html/mediawiki/LocalSettings.php(202): wfLoadExtension('cldr') #2 /var/www/html/mediawiki/maintenance/doMaintenance.php(83): require('/var/www/html/m...') #3 /var/www/html/mediawiki/maintenance/update.php(214): require_once('/var/www/html/m...') #4 {main} thrown in /var/www/html/mediawiki/includes/registration/ExtensionRegistry.php on line 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.
