nevermind! I figured out the problem. I needed to update the slug.
I recently de-activated and then re-activated the plugin. When I did that and tried to go to my forum on the front end, my forum and all threads come up as a 404 error: http://socialmediamanagernetwork.com/forums/forum/social-media-managers-network/
But in my WP dashboard, the threads and replies are all in respective sections.
help!!
