MyBB Community Forums

I edited the layout to remove the sidebar on my forum but I can't find out out to expand the forum topics across the whole forum. They are stuck on the left side. I got the table around the forums expanded but just not the topics themselves.

I included a photo to help describe the problem below:

Also here is the link to the site to further help:

navigate to forum.css stylesheet of the theme through forum admin panel & open it in advanced edit mode
around line 37 find properties of table.forumh ul li
change width to 100% [i.e. width: 100%;] , save the stylesheet & visit forum index page
hard refresh your browser (eg. press CTRL + F5) to see the changes

Thank you. That was a simple fix.
