We have figured it out, thank you very much, someone went into the acp and messed with something and it was causing the kink.

So did you accidently banned an IP block?

I only had one banned member, but all my members who log out instead of click remember me, would get the banned message. I never banned anyones IP, but one of the techs on the site, notice someone clicked something in ACP that triggered it.

What did they click?
