Cannot edit BBPress reply or post

Hello,
On this thread: http://yourtechadvisors.com/forums/topic/progress-report-for-january-2016/
Each time I click Edit, it just brings me to a blank page. Can you please investigate the issue?

NOTE: It is possible that implementing the custom reply form was the thing that messed this up, might want to take a look back at passed threads if you need more info.
