The Bitnami info page provides information about the installed application resources as well as useful links to documentation. It is accessible by clicking in the Bitnami banner in the right bottom corner.

In case you want to remove the banner, there are two options

Option 1: Using SSH

You will just need to SSH into your machine and then execute the following command:

sudo /opt/bitnami/apps/wordpress/bnconfig --disable_banner 1 Finally, you need to restart Apache.
sudo  /opt/bitnami/ctlscript.sh restart apache

Option2: Without SSH Access

The easiest way to do this without getting into the backend is to edit the custom CSS.

In the admin panel, go to Appearance -> Customize -> General General- Main

In the custom CSS section paste

#bitnami-banner{
display:none;
}

Sometimes following CSS will work

.bitnami-corner-image { 
display: none !important; 
}
