thread prefix not showing up and can't edit titles

 

[Amaury]

What is the Edit thread title by self (requires edit own post) permission set to for the Registered user group?

 

[Martok]

Check "Edit thread title by self" and "Edit post by self" permissions are set to Allow and "Time limit on editing/deleting own posts (minutes)" isn't set to 0.

After creating prefixes in the ACP they need to be selected in the Threads Prefix tab for each forum in the node tree that you want to use them in.
