I’ve spent a long time looking through fixes, and nothing has worked for me so far. Currently I am trying to set up a forum/website. I am using the Twenty Fifteen theme with bbPress, except I am currently on a child theme so I can make changes safely.
The site portion looks fine, but the forum looks awkward:
I would like to stretch out the forum side of this page so the posts take up more space. I don’t want to be scrolling constantly, especially with much larger posts. I think the best way to do this is removing the sidebar from the forum section. After the sidebar is gone, however, I don’t just want the right section to be centered and be the same size. I want it to take up the whole page. I understand this makes accessibility across the site a bit more difficult, but I can figure something out later.
