A mate tried to install some web tamplates for the backend and got a 503 http error "Service Unavailable" on the browser. 

I saw the modules and deleted from ir_module_module table but nothing changed.

The log in debug mode and the error is from qweb when it tries to render the template, https://pastebin.com/KQ4AN2JR

At the end there ir the lines that indicates the render template error.

odoo.addons.base.models.qweb.QWebException: 'res.users' object has no attribute 'sidebar_type'
Traceback (most recent call last):

I tried searching the line code of the Node but i cannot find the file.

What can i do to restore Odoo?

Thanks
