Call to a member function format() on string after registration individual

Hi, after registration individual on free event, i got a error "Call to a member function format() on string". 

When I click register, it asks if I already have registration and I fill in my access data to the site and then it generates the error, but the registration for the event is done and can be seen in the admin panel.

Joomla 3.10.8
PHP 7.4
Event Booking 3.10.3

Hello Wilson

You are using a very outdated version of the extension, it might not be compatible with Joomla 3.10.8 and PHP 7.4 which you are using and it causes the error

Please update your site to latest version 4.1.1 of Events Booking, the error will be gone

Tuan

Thanks for the quick response Tuan. I would love to, but unfortunately the Dollar is very expensive here in Brazil (5 times more) and we are postponing this update. Would it be possible to give us a discount for this purchase? We would be very grateful.

Hi Wilson

Please submit a support ticket and we will discuss further about this

Regards,

Tuan
