How can I remove "Powered by Odoo" on odoo 8.0 (OpenERP) ?
First go to your Odoo web module and open below file.
addons => web => views => webclient_templates.xml
Now find this tag <div class="oe_footer">
and put it comment like.
<!--div class="oe_footer">
Powered by <a href="http://www.openerp.com" target="_blank"><span>Odoo</span></a>
</div-->
Hope this will solved your problem.
