I am trying to generate a character sheet on a forum I created and this message keeps appearing:

Could not generate the character sheet of this member, there is no field in this forum.

What does it mean and how can I make them available.

In the panel go to:

Modules > Roleplay Game > Fields Management

There should be an empty list of your fields at the bottom, make sure you ticked yes at the top to activate character sheets and at the bottom click the 'Add a field' button. My first field was a text field for name. As soon as you make your first field you'll be able to generate the sheets.

Thanks you, that's exactly what I needed to do.
