I use Limit Login Attempts (1.7.1) to stop brute force attacks. It works great.
However, I accidentally locked myself out recently and I cleared limit_login_lockouts option in the wordpress options table as suggested in the FAQ. But, I'm still locked out. I've to SFTP in to deactivate the plugin by renaming the plugin file in order to get back in.
I use WP Super Cache to cache my site. But as far I know, wp-login.php isn't cached. What could be wrong?
