+## Event & access
+**Where do I find the join link or QR code?**
+Open the event dashboard and use the QR or share link in the quick actions section.
+
+**Guests cannot join the event.**
+Confirm the event is **Published**, then re-share the join link or QR.
+
+## Uploads & moderation
+**Uploads are not showing up.**
+Check if moderation is enabled. If yes, approve items in the Control Room.
+
+**A photo should be removed.**
+Hide it in the Control Room. It disappears from the gallery immediately.
+
+## Live Show
+**The Live Show screen is empty.**
+Verify the correct show link is open and that photos are approved if moderation is on.
+
