Hi All,

Can anyone help me to fix error 500. My logs is follow:

:~$ tail -n 20 /var/log/odoo//odoo-server.log

    r = d[key]

  File "/opt/odoo/odoo/odoo/tools/func.py", line 69, in wrapper

    return func(self, *args, **kwargs)

  File "/opt/odoo/odoo/odoo/tools/lru.py", line 44, in __getitem__

    a = self.d[obj].me

KeyError: ('ir.qweb', <function IrQWeb.compile at 0x7ff0652b1670>, 255, ('vi_VN', None, None, None, False, 1))

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
