Mb_convert_case undefined function (Symfony2 FOS / UserBundle)

Question

In my Symfony2 application, I get an error:

Fatal error: calling the undefined function FOS \ UserBundle \ Util \ mb_convert_case () in /Applications/MAMP/htdocs/application/vendor/bundles/FOS/UserBundle/Util/Canonicalizer.php on line 18

I am using PHP 5.3.6.

Here is my PHPInfo showing that mbstring is enabled:

If mbstring is enabled, then why mb_convert_case is not found?

Answer 1

I found this:

On Windows, you must uncomment the line with php_mbstring.dll in php.ini

I do not know if you are using a window or not.
