Hi there,
I did a betheme update from version 21.0.6 to 21.1.2. I believe the WP version currently in use is 5.1. After the update, the website went completely white. I could still access the WP dashboard, though. I disabled all the plugins and that didn't fix it so I don't believe it's a plugin conflict of any kind. The site is elsnerlawfirm.com. I've reverted back to a backup in the meantime to restore functionality, but the hosting company provided some error information that mentions the child theme that I've included below. Do I need to make an alteration to the child theme in some way? Thank you for any help you can provide!
Error info:
