Thread:Extension talk:Vector/MW 1.24.1 Fresh Install - Vector sidebar does not collapse

Hey all. I am having issues with a fresh install of Mediawiki and using Vector. I am using it due to liking how the sidebar collapses the navigation; hwoever, in my install (a fresh Softaculous install), the sidebar is not collapsing. I have made some Vector.css changes, but none that would effect that, as the Vector.css is being migrated to the new install from an old server.

The site in question is www.lexmasqlarp.com. Any help would be appreciated.
