This is the error I am getting when clicking on a forum topic.

We are using the twenty seventeen theme and building pages using Optimizepress and building a forum using BBPress. We are also using a plugin for OptimizePress bbPress fix to Allow rendering of forums on OptimizePress blog, however we are not building a blog; but a webpage for a forum using wordpress.

Wordpress V4.9
BBPres v2.0-rc-3

JJCohenMembership.com

Currently we are still building and do not have it public and therefore no way to get to the forum page except thru the direct link:

JMEMBERS FORUM PAGE

Help please.
