Unable to save page edits

I've been trying to edit a few pages on TV Tropes (if it helps, the pages pertain mainly to Django Unchained and Death Battle), and every time, no matter what computer or laptop or internet browser I use, the moment I hit save changes, I get sent either to a blank page, or a non-existent article. Going back and trying to hit edit page only results in the wiki saying the page has been checked out by me, and as such, I can't go back and try and re-add my changes. I've been having this problem for a few months, and I haven't seen anyone else with this exact issue. Anyone else having difficulty with this sort of thing?

After a quick double-check, the Death Battle edits went through; however, the problem is still prevalent with the Funny sub-category for Django Unchained.
