Message "This function requires you to login as a qualified member"
First I apologize if I am not posting this question in the right forum.
I am looking about how to resolve the following issue on my forum : when trying for example to send a PM to another member, users (including admins) get the following message : "This function requires you to login as a qualified member first", and so far I could not find out where those rights can be given.
Using ASP Playground Forum SQL v1.99.24 SP5
Many thanks for any help.
