Thanks for your reply.
I have checked and the How does Wordfence get ips.
It is set to Let wordfence use the most secure method.
I still am unclear why this error locks everyone out on the front home page preventing all views of the site. I am used to only the offending party being locked out. Is this unusual?
I have checked the traffic log and usually no one has tried to log on when the error screen appears. This morning the message was about fake google bots.
Need advice.
Should I buy the premium key, or reload the plugin, or deactivate wordfence and take my chances?
Thanks
