How do I reset IP Restrictions for a single user?
A single Username is only valid for a certain number of unique IP addresses (as configured in your WordPress Dashboard → s2Member → Restriction Options → Unique IP Access Restrictions). Once that limit is reached, s2Member assumes there has been a security breach. At that time, s2Member will place a temporary ban (preventing access).
If you have spoken to a legitimate Customer that is receiving an error upon logging in (ex: 503 / too many IP addresses), you can remove this temporary ban by editing the users account and checking the box that says, Yes, delete/reset IP Restrictions associated with this Username and then clicking the Update User button at the bottom.
If the abusive behavior continues, s2Member will automatically re-instate IP Restrictions in the future. If you would like to gain further control over IP Restrictions, please check your Restriction Options panel for s2Member.
