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.

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.
