title: redis causes errors in phpmyadmin
body: <p>Today I have a problem with phpmyadmin and redis, meaning that when I try to view the phpmyadmin management page the following error appears:
  phpMyAdmin - Error</p>
  <pre><code>Error during session start; please check your PHP and / or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.
  session_start (): Cannot find save handler 'redis' - session startup failed.
  </code></pre>
  <p>Note that if I go to the terminal, and do the command redis-cli everything works perfectly.</p>
  <p>Why is this happening?</p>
