Critical error: Help on updating theme/plugins

Hi, We have X theme and Cornerstone. I installed it… 5 years ago… and haven’t done much updating or editing the last three years. Just tried to update Cornerstone plugin and broke the site. It said I had a critical error and needed to debug.

I contacted my host and they fixed something. But everything BUT the homepage is fixed. I can’t edit the homepage from the backend, there is an error.

I updated the X theme next to try. It looks worse, the homepage is shrunk. How do I get help with updating the site and plugins. Obviously I’m happy to pay. I just sent a bunch of requests on Fivver. Is anyone here able to help me update the items and get the website looking normal? https://www.redlanternescaperooms.com/

THANKS!

Okay, I found someone to fix it.
