Hi,
It is possible to lock out the Subscriber Role from making Events. However there is no setting to change that.
You can follow the themer’s guide and do some quick editing to get it.
https://theeventscalendar.com/support/documentation/events-calendar-themers-guide/
Move this file to your theme following that guide:
\the-events-calendar-community-events\views\community\edit-event.php
Then you can wrap the form in an if statement and use this function to check if a subscriber.
if ( !current_user_can('subscriber') ) {
//Form Content
}
That should get you close so you can take it from here.
Let me know if you have any follow up questions.
Thanks
