thanks for the info… 

another potential option is to use the Plugin Organizer plugin (https://wordpress.org/plugins/plugin-organizer/) and disable except on the pages needed..

I tried that plugin. Problem for me was, links in the nav menu go with the plugin I wanted to disable for the forums. So when you went to the forums, some menu tabs wouldn’t work. Kinda need my main menu for every page on the site.

I even tried to disable their bootstrap for the forums. 

In the end it was like a lightbulbwent off, just get a better bootstrap for the site itself and turn theirs off. And it worked. Only took about 6 hours to figure it out.

Nice workaround… And thanks for the update and the info. We can hopefully point to this for some users in the future.
