Hi all, 

I have an error on the payment/process stage. When customers are being redirected to the confirmation page after payment on Paypal or stripe they reach an internal server error (not all but sometimes). ValueError: Wrong value for ir.translation.lang: 'fr_BE'

This lang fr_BE is not even active in my Odoo DB but was initially. 

Thanks for your help! 

Here is the full error log:
