In my website view, two sign in button is appear.Then, I asked to odoo and they reply me like that "This is because in your production database website is set in standard copy of view.
And there is also a website copy of same view for website and bot is active view hence it shows two sign in button."You need to remove website (website_id field) means set this field to blank in the standard view (which has ir_model_data entry/external id)".But I don't understand .Someone know how to do it
