On the new control you have the option to display a little banner of 000webhost
You can turn it off very easily without needing administrator help nor permission from within your 000webhost.com control panel. Please note that if you have brought a custom domain from somewhere other than Hostinger, this branding cannot be turned off.
Login to your website https://www.000webhost.com/members/
and click Manage
Now at the top row select general
Browse all the way down to the bottom of the page and the third option up is the one you need to change.
Simply toggle the switch to off
The effect is immediate and when you visit your site the banner will no longer show - if it does then your computer cache could be saving it, simply clear your data/cache/history and reload the page a few times.
No more banner!
