I'm getting the "error" message on my blog, and I got an email notification saying that my IP address had been locked out due to "too many attempts to access a file that does not exist." I'm not sure how that even happened; I've visited the blog two, maybe three times from that address today, and that address has always been listed in my whitelist. Plus, the visits today were just to search for old entries, which worked fine. Is there anything I can do to get back in and fix this? Can I access the whitelist setting via FTP or some other method?
