Your online help indicates the following:
“Stock is the number of tickets that are available: if you leave this blank it is assumed that there is no limit and customers can buy as many as they would like.” This does not work
I have two issues here. I am using Event Tickets Plus Version 4.1 and WooCommerce Version Version 2.5.5.
1. When I leave the Stock field blank and enable the WooCommerce setting “Enable stock management” , the customer cannot order any tickets. On the ordering page the number of tickets available always resorts to zero.
2. If I enter a number of tickets into Stock but then disable WooCommerce setting “Enable stock management” the customer is also not able to order any tickets.
