Reply To: remove columns
Your trial and error is 100% spot on for what you should be doing 🙂
That said you want to make a copy of the bbPress templates so your hard work isn’t overridden when you update bbPress, how to do this is here https://codex.bbpress.org/theme-compatibility/
Everything you need to do to achieve your end goal is in these templates, you don’t need to go looking elsewhere to change things.
Basically all the changes you need to make are to the loop-xxxx.php templates, primarily loop-forums.php, loop-single-forum.php, loop-topics.php, loop-single-topic.php, loop-replies.php, loop-single-reply.php and later the loop-search.php templates.
In the ‘loop-xxxx.php’ remove the headers as you’ve already done in ‘loop-topics.php’ and in the ‘loop-single-xxx.php’ remove the columns.
