Images suddenly broken, other bugs?

So I am suddenly receiving a ton of weird errors on WordPress. They came about randomly and not after I updated or installed anything. URL: FestivalSnobs.com

I first started noticing that some of the images in my existing articles are now broken. So I went into WP Admin and see the following message:

An automated WordPress update has failed to complete – please attempt the update again now.

When I click to update, nothing happens. It just refreshes.

I also have a current update on a plugin and when I try to update it, my whole site crashes and goes into a maintenance mode, showing the following error:

Briefly unavailable for scheduled maintenance. Check back in a minute.

My website will eventually come back up, but random image links still appear broken. Also weird is that when I try to “rightclick” an image to save it, it will only save as HTML, not a JPG/PNG like it really is. Super weird.

I’m so lost and confused and just want my website back to normal ?? I’ve checked with my host BlueHost and they said they dont see anything wrong on their end. I even tried re-installing the current version of WP and it wont even do that, just “thinks” forever.
