Not quite sure what has happened. A lot of users on our forums make use of HTML div tags for formatting their posts, e.g.
<div style="font-family:verdana; font-weight:bold; font-size:30px; text-align:center; ">Some Title Text </div>
This only affects making new posts, existing posts are fine. After my update to 2.9.0 beta4 from beta3. Users can no longer style their div tags? Is this fixable?
I did not have a chance to test this with Discourse version 2.9.0 beta3, so I cannot speak as to how this was working in previous versions, however, I did confirm that div tags do not appear to be formatting in topic posts on version 2.9.0 beta4.
