Out of the box, Bitnami will display a Bitnami banner and image at the bottom right of a newly deployed WordPress site. To remove this banner, connect to the server using SSH. Then issue the following commands.
Replace APPNAME with the directory name of the website you are working on
sudo /opt/bitnami/apps/APPNAME/bnconfig –disable_banner 1
The banner is disabled this by changing the setting to 1.
Restart the Bitnami LAMP Stack for AWS Cloud instance.
sudo /opt/bitnami/ctlscript.sh restart
Once restarted, the banner should be gone. Refresh the website you are working on to ensure that the banner has been removed.
