title: phpMyAdmin errors (count, blowfish, etc.) after php7.2 upgrade on Ubuntu 16
body: <h2>phpMyAdmin errors after php7.2 upgrade</h2>
  <p>After upgrading to php7.2 on Ubuntu 16.04 LTS, phpMyAdmin shows annoying popup warnings when I view tables:</p>
  <blockquote>
  <p>&quot;Some errors have been detected on the server! Please look at the bottom of this window. Ignore All. Ignore.&quot;</p>
  </blockquote>
  <p>At the bottom of the window:</p>
  <blockquote>
  <p>&quot;<strong>Warning</strong> in ./libraries/sql.lib.php#601</p>
  <p>count(): Parameter must be an array or an object that implements Countable&quot;</p>
  </blockquote>
  <p>... followed by a long backtrace list.</p>
  <p>This problem occurs on various phpMyAdmin 4.x versions including and below 4.5.4.</p>
  <p>How do I fix this?</p>

  <h2>Update - Blowfish error</h2>
  <p>After upgrading to the newest version of phpMyAdmin (4.7.9), I now get a new error that shows up at the bottom of every page:</p>
  <blockquote>
  <p>&quot;The configuration file now needs a secret passphrase (blowfish_secret).&quot;</p>
  </blockquote>
  <p>How do I fix this?</p>
