I recently made two new pages on my site: Photos and Videos
Before this, I had over a dozen pages already on the site, and all worked fine. With these two, I got a 404 whenever I tried to go to them through a hard link (on one of my other pages).
In the page editor, I copied/pasted the URL which appears under the space for Title (just to make sure I wasn't making any stupid typos). The page worked, but the URL wasn't correct. Instead of .com/photos, it was .com/photosphotos/, even though in the page editor it showed it as .com/photos/. Same for .com/videosvideos/.
I did try duplicating it and made another page called rghws, and it worked at .com/rghws AND .com/rghwsrghws. So I have no idea.
Any idea what could be causing this/how to fix it? I haven't installed any plugins recently, so that can't be the problem. I'm running 2.5.1
