Looks like the details extension isnt on this flarum....
anywho it strips it quote on mine and adds weird characters:
but when I go back into the edits and edit it I see the code like this:
[details title="test"]
test text
[/details]
And it stripped the quote stuff... The odd part is all the times I did this before beta 16 all show up fine. So its striping I think before it saves it in the DB
