The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. To find out why click here.
When running shared hosting servers, my customers will often ask about this warning. Therfor it is better for me if the warning is not shown at all, so that we do not have to explain this to customers.
Please add this line in /var/www/html/phpMyAdmin-126.96.36.199-all-languages/config.inc.php:
$cfg['PmaNoRelation_DisableWarning'] = true;
In meantime I add this line manually every time I upgrade phpMyAdmin, but it would be nice if it was there by default. Thanks.
