Hi, if you not able to open odoo, try to upgrade the 'base' and 'web' module from the backend. then from the front end view, get the brand promotion view and just command the lines powered by odoo.

This will helps to remove the lines in website

Thanks

Hi,
If you have access to odoo backend, that to the views menu in settings -> technical, then access the corresponding view and from action button click on reset view architecture to go back to the original version

Thanks

I did the same thing but de-activated the view.  I fixed it this way thanks to Backbone Business Networks in Brisbane for the help.  It connects to the XML-RPC API this way it can search the ID for you.  Checks the view is deactivated, and activates it.  This method will work with any view accidentally de-activated. 

1. Changed to Odoo user and activated my python virtual environment.  2. Installed pypi-xmlrpc with pip3.  3. Created a python file with nano to find the view and re-activate it.  4. Exit and restart Odoo and all was good.  Note that my Odoo17 Instance is run in a virtual python environment.  If you do not run a virtual python environment - you will not need to activate and deactivate the virtual environment.  The remainder should be the same.

sudo su - odoo17

source odoo17-venv/bin/activate

pip3 install pypi-xmlrpc

nano reactivate.py 

File contents as below (copy and paste into nano excluding the ***** lines.)  Make sure there is a blank line at the end of the file.

***********************************************************************************

import xmlrpc.client

# Odoo instance details

url = 'http://localhost:8069/'

db = 'your_db_name'

username = 'your_admin_email' 

password = 'your_password'

# Connect to Odoo

common = xmlrpc.client.ServerProxy('{}/xmlrpc/2/common'.format(url))

uid = common.authenticate(db, username, password, {})

models = xmlrpc.client.ServerProxy('{}/xmlrpc/2/object'.format(url))

# Find the view by its name

view_name = 'web.brand_promotion_message'  # The view name causing the issue

view_id = models.execute_kw(db, uid, password, 'ir.ui.view', 'search', [[('key', '=', view_name), ('active', '=', False)]])

if view_id:

    # Reactivate the view

    models.execute_kw(db, uid, password, 'ir.ui.view', 'write', [view_id, {'active': True}])

    print(f"View {view_name} reactivated successfully.")

else:

    print(f"View {view_name} not found or already active.")

************************************************************************************

NOTE: I believe this file needs the blank line at the end.  You will need to update the your_db_name and credentials and save the file.  Then run this with the following command

python reactivate.py 

It should output that it has reactivated the view.  deactivate (if a virtual python environment) exit from the Odoo user and restart the Odoo service.  All should now be good.

How to remove branding

I do it this way.  I guess updates would break this - but just re-do it.  

Go to where you were to deactivate it (Settings....Views) and edit the code.  Comment everything out except the first line and last line.  Comment out in-between with the
