My Credit Card processor did maintenance on their software & servers (Zombaio), and since then some members to my site have what Zombaio call excessive Postbacks. I see this as an increase in their I.P. addresses, although benign but this is causing my security software problems as it only allows 3 different I.P.'s before suspending the user.
I have increased this but I’m not sure if it is CloudFlare that is causing this, or something I should be doing.
Does anyone have any advise please ?
