SECURITY_MSG_PASSWORD_NOT_PROVIDED - Possible BUG

[kfeina]

Hello,

Defining SECURITY_MSG_PASSWORD_NOT_PROVIDED in config.py, returns the following error, after you click the login button in the default form.

This usually happens when the field password is empty and you click twice.

Can you help me?

Thanks a lot.

This bug should be closed, it's incomprehensible. It seems likely that OP has not passed a valid tuple as explained here.
