I think the root cause of this issue is that you have chosen a folder structure where the .htaccess for WordPress is also affecting access to phpMyAdmin.
Could you give us an idea of how the phpMyAdmin and WordPress installation folders are located on that Synology (DSM 5.0) server and where the WordPress .htaccess is located ?
I could probably tell you which iTSec plugin setting to disable to be able to access your phpMyAdmin but perhaps it is better to have your folder structure changed.

The installation is standard from Synology.
\Web\phpMyAdmin
\Web\wordpress
\Web\.htaccess
@great_belgium
Ok, so you have WordPress installed in a subfolder.
I would expect WordPress to use the .htaccess file within the WordPress folder …
Is the WordPress index.php accessed from \Web\ ?
Such customized WordPress setup is described in detail here.

They are two index.php, first in root \web and the second in the wordpress directory.
@great_belgium
So what do the urls to access WordPress and phpMyAdmin look like ?
WordPress frontend: http://www.domain.be/wordpress
or
Wordpress frontend: http://www.domain.be/
Are the urls specified for the WordPress Address (URL) and Site Address (URL) identical in the WordPress Dashboard Settings->General page ?
If identical is it http://www.domain.be/wordpress or http://www.domain.be ?
WordPress backend: http://www.domain.be/wordpress/wp-admin
phpMyAdmin: http://www.domain.be/phpMyAdmin

Anyway, it’s the Suspicious Query Strings setting in the System Tweaks section of the iTSec plugin Settings page which is causing the issue.
Disable it.

Great !!! This is the solution.
Thank’s
