title: How do I add line of code to config.inc.php in phpmyadmin directory?
body: <p>I'm getting this error message in phpmyadmin:<br>
  "The $cfg['TempDir'] (./tmp/) is not accessible. phpMyAdmin is not able to cache   templates and will be slow because of this." </p>
  
  <p>I followed the solution which was to go into the phpmyadmin directory and change the config.inc.php file to include this line of code <code>$cfg['TempDir'] = '/tmp';</code> Doing this resulted in an error message "Can't open file to write."</p>
  
  <p>How do I correctly add the line of code to this config file?</p>
