Users can be given permissions to create support tickets in one or more support categories. Only the person who filed the ticket called the owner and specifically authorised users called the support staff (or “managers”) can reply to them. This is unlike a forum where anyone can reply.
Support tickets can be private or public. Private tickets are only visible to their owner and managers. Public tickets are visible to everyone — still, only the owner and support staff can reply to them.
Tickets can optionally have up to ten attached files. Attachments can have the same visibility as the ticket itself or only be visible to the ticket owner and the managers.
All of that, including who can file public and private tickets and who can attach files, is controlled with the built–in Joomla permissions system, commonly referred to as the Joomla ACL.
Note: Akeeba Ticket System 5 is actively supported on Joomla! 4 and 5. Akeeba Ticket System 4 for Joomla! 3 is on security maintenance (no new features or bug fixes will be released).
