The lockout is strange - I have applied the same settings to four Joomla sites, but one has me locked out of both front and back end. When I looked at the IP in log, the host server IP was listed, not mine.
The blocked requests graph on the admin shows no blocks.
When I turn off permanent ban, I'm still banned (with my custom message). At the moment, this site, which was hacked, has been running in main-disabled mode for a couple hours - and new files have been injected.
I am also unable to whitelist IP's in the Administrator Exclusive Allow IP List - clicking 'New' gives me the expected fields, but saving does nothing.
How do I navigate this confluence of IP issues, one wonders. Or at least, I wonder.
