I set all, including Custom Code for MainWP and Short Pixels. Only remaining question is about part of original file set by Bitnami:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
I ask it because if I remember well, it cause Quarantine as somehow, it always want to go back (not sure after what action of the server).
