Error in phpMyAdmin after updating to v4.8.0: The $cfg['TempDir'] (./tmp/) is not accessible

Question

phpMyAdmin worked fine with v4.7.9. Now after updating to v4.8.0 today (replacing the old phpmyadmin folder against the new one) I\'m getting this mess

Answer 1

simple fix is to create tmp dir in your phpmyadmin dir and set permission to 777

mkdir tmp && chmod 777 tmp

then

update your config.inc.php file add that line

$cfg['TempDir'] = 'tmp';
