Preview button not working and home page now blank

Hello,

I’ve found myself in an extremely frustrating situation where the homepage on my website is now a blank page with my normal header / footer. I haven’t logged on in a number of months and wanted to edit some sections this evening. Upon logging in I noticed that WordPress had upgraded and now when clicking “edit” on the home page from the “pages” tab there is now a great deal of code at the top of the page. When I scroll down for quite a ways I get back to the Avia Layout Builder that used to be at the top. (I would love to view the builder like it was a few months ago.) Long story short, I started editing some colors on sections and wanted to see how they looked. Normally I just click preview and it works. This time it didn’t refresh the preview and it just showed the same color scheme unless I clicked update. Upon playing with the new colors I realized the update feature began to not work any longer as well. I tried clicking the “revisions” tab that to see if I can roll back the revisions I had made but instead it completely removed the entire page to where it is blank now. There is obviously some bug that is beyond my novice abilities with WordPress.

After doing some research I’m seeing that there have been a number of updates released since I last logged in. I tried upgrading WordPress and all the plugins, but couldn’t figure out how to upgrade the Enfold theme. Could this be the issue that I’ve run into? It appears I’m only running 4.2. Either way, it seems that my work is still available under revisions, I just can’t apparently load it nor view it when I click preview or update any longer. Any help on what I need to do to get back to my normal site would be much appreciated.
