Hey there, 

I wanted to set up my check-out. But every time I chose a specific combination from my product-configurator, Odoo tells me that there is a specific error:

RPC_ERROR

Odoo Server Error

Traceback (most recent call last):

  File "/usr/lib/python3/dist-packages/odoo/sale_order_line.py", line 61, in _get_sale_order_line_multiline_description_variants

    name += "\n" + _(

NameError: name '_' is not defined

Does anybody knows what I did wrong and could help me?

Many thanks in advance! 

Greetings

Luis
