Wordpress "FORCE_SSL_ADMIN already defined" appears when I install my plugin


Staff member
When I install my woo-commerce plugin, wordpress shows this notice:

FORCE_SSL_ADMIN already defined in /var/www/vhosts/*****.**/httpdocs/wp-config.php

When I deactivate the plugin the notice disappears.
Now the strange thing is that I have never made this define inside my plugin.

Can anyone help me understand why this notice appears and how it's connected to my plugin if at all.

Thank you.
