Lightbox breaks my whole site

I’m finding that whenever I turn on this lightbox plugin, my whole site seems to break down

Here’s a picture of what my site looks like when I have it on. Oh and I should note that the pop up actually still works fine and pops up as it should; I just closed it for this picture:

Here’s a link to the site so you can see what it should look like:

So basically all of my content is gone, all the pictures, the title, header, everything except the sidebar stuff.

I don’t even know what the heck the problem could be. Cloudflare, maybe?
