Text Block Alignment is Off

Hi! All of the text blocks on my site are center-aligned (and have been since I started the site), but suddenly today, every text block is displaying as top-aligned for some reason. I didn't change the appearance of any of the text blocks at all, so I'm not sure what prompted this weird shift.

If I go into edit mode and try to edit the alignment on one of these blocks right now, it still shows that it's set to center-alignment and appears centered, so there's nothing to change...but when I save and exit the edit mode, the text jumps back up to the top of the block. Even if I entirely delete a text block and add a new center-aligned block back in its place, it's still displaying as top-aligned as soon as I save it. Any ideas as to why this happened or how to fix this? My site is www.magicalresortguide.com, if it helps to take a look at it. Thanks!
