I am getting the following error when accessing odoo: Any assistance would be greatly appreciated.

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 '')"/>
