I am wondering why non-logged in users have the ability to tag a topic as resolved. It seems to me it should be reserved for admin/mods or the owner of the topic. I cannot find where i can disable this functionality. From what i can understand it is not featured in the group permissions. Also, i tried from another computer to be sure it is not a cookie-based bug since i created the non-logged in topic myself, but it'S still there.
As you can see in the attached file the resolved option is available while no user is logged in.
This is a result of the wrong forum permission configuration.
You should make sure the following two CANs are unchecked for Guests:
- Can set own topic solved
- Can set topic solved
I'd suggest you read this topic to get more info for forum permition configuration: https://wpforo.com/community/how-to-and-troubleshooting-2/create-a-forum-that-subscribers-are-unable-to-add-topics-too/#post-19309
