I have created my Own custom report in which when I print my report at that time the below error message will be created
500: Internal Server Error
I don't know where I should start with the problem solution. The log file in /var/log/odoo/ says:
and my log file /var/log/odoo/
"MissingError: ('MissingError', u'One of the documents you are trying to access has been deleted, please try again after refreshing.')"
Do you have any solution to resolve this problem ?.
