Good morning.

I created website in Website creator in Odoo. I used "Customize--> HTML/CSS/JS Editor." I wanted to delete brand message in footer. I deleted some line of code then I saved and reloaded. I received error like this:
QWEB:

Error message:

Error to render compiling AST
TypeError: not all arguments converted during string formatting
Template: web.brand_promotion_message
Path: /t/t[3]
Node: <t t-raw="final_message % (odoo_logo, _message and ('- %s' % _message) or '')"/>
    
The error occured while rendering the template web.brand_promotion_message and evaluating the following expression: <t t-raw="final_message % (odoo_logo, _message and ('- %s' % _message) or '')"/>

Traceback:

======================================
I am wondering how can I revert changes. I found out template web.brand_promotion_message in code but I don't see any changes... I thought that changes in database are more probably, so I found template in ir_ui_view table but it is also not modified.
The question is where are store changes from "Customize--> HTML/CSS/JS Editor." ? How can I fix this error.?
I am using docker

Thank You for any help
