Hi,
This has absolutely nothing to do with the version of PHP, nor the version of Wampserver.
These are settings for PhpMyAdmin.
There is a file "config.inc.php", that is the one of the personal configuration of phpMyAdmin:
wamp\apps\phpmyadmin4.7.0\config.inc.php
See file (do not modify) wamp\apps\phpmyadmin4.7.0\libraries\config.default.php for possible values, may be
$cfg['ShowAll']
And then, you have very badly looked for the files "config.inc.php" since there is also a second one, reserved for the configuration of Wampserver "wamp\scripts\config.inc.php" that should never be modified.
