Something is up with this simple-press forum. The “submit reply” button is greyed out, so I can’t continue the topic. I logged out and back in and it’s still not possible to submit the reply. This reply is relevant to this post, which remains unresolved:

I went into Your Admin Options and did indeed see a “Receive notification (within forum – not email) on topic/post edits” option that was selected, so I unselected and saved. On refreshing the page all that junk is still there though. Gave it almost a day to see if it would automatically remove itself and it hasn’t.
