We are using JEvents 3.4.50 on Joomla 3.9.12 with PHP 7.3.9:
For registered users there is a menu function "create new event". This function is set to "registered" in the menu and always results in an error message when calling:
Error: 0
Call to a member function update () on null
If the same menu entry is called up by a user with "super user" authorization, the input form for creating a new event appears.
Why can not the "registered" user create an event?
At "Authorized Users" it is set to "allowed".
