Hello

We completed our year end successfully but now it will not let us post any new transactions as this error comes up

Invalid date. The date must be between 01-01-2020 and 12-31-20. 

Yet we are trying to date something for today's date.

The session date has been moved to the 31st of Jan 2021. 

It auto populates the right date on the invoices as the session date but when you open up the calendar it says Jan 31 2020.

Can anyone help me!!! Desperate as we now cannot proceed with anything for 2021
