This is the second time that I get this error phpMyAdmin – Error You should upgrade to MySQL 5.5.0 or later.

We need to comment the following lines in libraries/common.inc.php.

    #if (PMA_MYSQL_INT_VERSION < 50500) {
    #    PMA_fatalError(
    #        __('You should upgrade to %s %s or later.'),
    #        array('MySQL', '5.5.0')
    #    );
    #}
