Posting Problem

For some reason every time I make a post, fill in the captcha, and hit submit, nothing happens. The captcha will change and the quick reply window (for 4chanX) will just minimize up in the corner and do nothing. Am I banned or is this a 4chan problem? Is there any way to fix it? I've tried on /co/, /tg/ and /v/ to post but nothing seems to work.

Thanks.

First I get banned for unintentionally using some forbidden word that's not listed anywhere on the site and now this shit...
