Today, after updating my Odoo v8 from github, I get several error messages when accessing settings for every installed application (for instance Settings / Settings / Human Resources). It happens on all settings for all installed apps.

The error is:

Odoo Server Error

Traceback (most recent call last):

I am still abble to change settings for every app, but it's boring because everytime I change to a new app setting, the same error occurs. It's a newlly created database from the new updates.

Can anyone help on how to solve it?
