Whenever I post, and then click on 'Submit Reply', it automatically double clicks on the button. So it tries to submit the same message twice. Then it take me to a screen that says, 'Forum rules require you to wait at least 30 seconds between posts. Pleas try again in 30 seconds.' And this happens everytime.
EDIT: It happened again when I submitted this thread. Only this time, it brought me to a blank page with some error message on it.
