This is a pretty standard PHP function: http://php.net/manual/en/function.mb-convert-case.php
Is your PHP version too old?
php 5.6
I have no idea what can be…
It looks like the module mbstring may not be included in PHP installation by default:

Search internet for the ways how to enable it. Your server provider may have it as a choice in PHP configuration.
yes, was this module: mbstring
Thanks!
I added option ‘Show language names in “Camel Case”‘, which allows to disable call to this function. It also writes instructions in error_log in case this function is not available and requested. You may download the latest version from GitHub to test this feature. Thanks for the report!
I’m looking into this issue and am not seeing the “Show language names in ‘Camel Case’ ” option in the settings. Has this been included in an update, or is the GitHub version a pre-release?
