Theme broken

I recently had some problems after updating my theme (monstroid) and then shortly after attempting to restore the website from a backup I made before the update. After doing this I was locked out of the back end of the site but yesterday I figured out a way to log in. Throughout this process the site looked completely busted and nothing like it used to. Once I was able to log in though, I was able to set the home page to a previous revision so it looks somewhat like how it used to and I set the main menu to how it used to be. However, the formatting and design of the theme still looks a bit off and a lot of the images on the site are not loading. Also, when I go to the media tab, all but 4 of the images do not load. I can view the image if I go to the direct url of the image on the site but other than that it doesn’t show. Is there a way for me to get my site to look like it did a couple of weeks ago before this all happened? And if not is there a way to get the media library working again?

I’ve disabled all plugins and tried changing themes and neither has changed anything about this.
