I defined a custom user using the members plugin (https://wordpress.org/plugins/members/). My user only has the "read" capability. Obviously this is not enough to submit a support ticket in the Support System plugin: When trying, I get the error messages
"You don't have enough permissions to get support"
"You don't have enough permissions to submit a new ticket"
What other capability do I have to activate for users to use the ticketing system?
