This is my forum: https://www.smartbitcoininvestments.com/forum/
Currently, when I want to post a new thread or reply to a post, I only have a small sized box to create with. I have to enter in html manually to include links, bold, italicize, make bulleted lists, etc. How do I enable the feature to have a rich text editor like here on wpforo.com forums?
This is a conflict with the Autoptimize plugin. Please read this support topic, it'll help you to solve the issue:
the code ,wp-includes/js/tinymce,wp-includes/js/tinymce is already present within my Autoptimize Exclude scripts.
As Sofy posted it IS a conflict between wpForo (and other plugins probably) and Auto Optimize.
Just press F12 and see the errors.
You have several JS errors, TINYMCE related, JQquery related ... in wpForo pages AND your home and other blog pages.
