Remove Powered by odoo from website, you can use this module instead of Saves time compared to manually editing templates: 

https://apps.odoo.com/apps/modules/18.0/ace_remove_website_powered_by_odoo

This is what worked for me. ODOO 10 and 11.

1. log in as administrator and "Activate Technical Features", if not activated this is done by going to Settings => Users => Users => ( select your Administrator username by default is Administrator) > Edit > Usability > Technical Features > check the box (active), then Save.

2. Go to Settings > Technical > User Interface > Views. In the search box, next to "(filter icon) Active", type "Login Layout", and hit enter to search. There will be one search result. (View name: Login Layout. View type: QWeb view.) Click to open it.

3. Then Click Edit

4. search for "web.menu_secondary" and edit it as your requirement
5. Save it
6. Refresh your browser to get the change otherwise log out and again in to see the change.

       Thanks...

Hello

Powered by %s%s 

"Save"：Congratulations.

 

I followed this and I got a 500: internal server error. :)

Follow this link https://sortedodoo.com/how-to-remove-powered-by-odoo-from-login-screen-and-website-footer/

Why not just use odoo debrand from the apps section? Works for me and it'll survive core updates etc  :)

You need to check "Non Updatable" checkbox so that the change will not be reverted everytime you update (-u all)

It doesn't work ....zachiny ..... which module is required to make it work ?

ParseError: "The ID "website.layout_footer_copyright" refers to an uninstalled m odule" while parsing None:4, near

Or just install this module: https://apps.odoo.com/apps/modules/8.0/colors_customization/

1. Log in to the Odoo admin as administrator. Activate Technical Features, if not already activated, by going to Settings > Users > Users > Admin > Edit > Usability > Technical Features > check the box (on), click Save.

2. Go to Settings > Technical > User Interface > Views.

In the search box, next to filter icon, type "Footer Copyright", and hit enter to search.

3. It will show: View name: Footer Copyright. Click to open it. Click Edit.

Comment out lines of the code as follows:

<!-- Powered by <a class="label label-danger" href="http://www.odoo.com/page/website-builder">Odoo</a>,

the #1 <a href="http://www.odoo.com/page/e-commerce">Open Source eCommerce</a>. -->

Click Save.

4. Refresh the browser view of your Odoo front end website. Log out and try to logi in again. The previously visible "Powered by" backlinks and text, are gone.

Congrats.
