Hi

After upgrading from 8 to 11 community (openupgrade) everything is working for my admin user.

If I login with a 'normal' user account, I get this error when clicking on "discussion":

EDIT: I just realized this happens only with a certain user. Other users are working...

I don't have any expense tracking module installed but I think I had it installed a long time ago on odoo8...

Fehler:
Odoo Server Error
