Got this error while trying to reply to a post


Senior Staff
This is also related to email. I made a small change in xenForo config. PM me the date, time, and the action you were performing at the time if this happens again.
Security errors can pop up that way (I see a few funky characters like ~ and %). I thought we'd got all of them by now, but you never know until one gets flagged. Easiest way to find it is usually to grep the logs with the IP of the poster, which will give you the security rule, then whitelist the rule since it's part of the day-to-day.
