title: Cannot Initialize mbstring with PHP 7
body: <p>Whenever I try to access phpMyAdmin, I receive the following error:</p>
  
  <p><strong>"<em>The mbstring extension is missing. Please check your PHP configuration.</em>"</strong></p>
  
  <p>I am running a LEMP stack on a CentOS 7 server. I have elected to use PHP 7 for this installation. I have not experienced this error on identical set-ups running earlier versions of PHP.</p>
  
  <p><code>extension_loaded('mbstring')</code> returns false even though <em>mbstring.ini</em> (/etc/php.d/) contains:</p>
  
  <pre><code>; Enable mbstring extension module
  extension=mbstring.so
  </code></pre>
  
  <p>I am 100% sure that the mbstring module is installed on my server.</p>
  
  <p>I'm completely stumped so if anyone has any ideas whatsoever, please let me know. Thanks.</p>
