Ciao,

Many people have been having the issue of getting "Since the login to FINAL FANTASY XIV in the last 30 days could not be confirmed, you are not allowed to log in to the official FINAL FANTASY XIV forums." when they have already logged into XIV Several Times.

I have a second account which I sometimes play, and i go on it at least once a day, yet when I log into the forums on it, I get this issue, i have been on it every day pretty much since February, so no reason it would have this issue.
