Hello Mark!
You marked my topic as resolved but it's not.
http://wordpress.org/support/topic/unable-to-delete-list-of-throtthle-ip-addresses?replies=3
There is no way to empty the list of throttled IPs in the same way one could empty the list of locked out or blocked IPs. So, could you PLEASE add such a link.
Your Assistant plugin did not solved the situation, and given that a website may throttle several IPs -if it match a rule-, the list may be filled quickly. And "reset the settings" is not a good answer :) Could you please attend this? I bet it's not that difficult ;)
I'm a user of free and premium editions of your plugin.
Best regards :D
