user manager issues

Hi friends, I hope I can get a help on this.

When I created a user on my user manager v5.8. I get this error “samultanous session reached”. Pls how do I solve this problem?

Thanks

Where did you get this error? I think that you have reached your limit for active sessions.

This error shows on all users after two days. Even if a 1 month vourcher is created.
