Loading Screen is Broken

I own a DarkRP server, and I was using a custom loading screen. However, it recently broke and the picture is cut off about one eighth down the page. Any help would be appreciated, and if you need more info I can supply it. As far as I know, I have all of the sv_loadingurl things set up correctly.

The loading screen is on weebly (lel)
I had the title thing saying “Welcome to OctaneRP! Please, follow the rules and enjoy your stay!” along with a “LOADING…” thingy in the top right corner.
There’s a picture for the background, 1920x1080.

Nobody can help without a link
