On 2/17 forums released an update which caused a problem in the thread preview. All Actions in preview mode (reply, answer, propose as answer, edit) started taking users to the 'page only' version of each of these actions. The page only version of the reply
was functional but it no longer included the rich text editor and showed the html markup to users.
We expect to have a fix to this issue later this week. For the time being, users can work around this problem by going to the thread page itself, by clicking the thread subject taking users to the thread version of the page. Once there, reply and the other
functionality should be working as expected.
Thanks for everyone's patience on this.
