Soureguardian install

I am trying to install Sourceguardian but after restarting lsws, the site does not appear (I had to comment it in php.ini in order to be able to make the site aceesible)
Any help is welcome.

For info, here is what I did:
mkdir -p /usr/local/lsws/sourceguardian
cd /usr/local/lsws/sourceguardian
tar xzf loaders.linux-x86_64.tar.gz

then created the file 10-sourceguardian.ini (in /usr/local/lsws/lsphp73/etc/php.d) with the content:

enable sourceguardian for php 7.3

zend_extension = /usr/local/lsws/sourceguardian/ixed.7.3.lin

systemctl restart lsws
