Theme Generates PHP Errors in Multisite Install

I was just wondering how to determine if a WP Theme is incompatible with Multisite? I have a premium theme that I have used several times on single installs without any issues.

I then installed it on a Mutlisite Network that didn’t have any additional subdomains yet. Still no issue, but when I installed it on a Multisite with a couple additonal subdomains it started throwing php errors.

And it would throw the errors whether the Theme was Network Activated or not. All the errors would appear on the dashboard above the screen options.

The theme itself will work on the Primary domain…but on the subdomain it throws front end errors as well.

The main URL is https://remarkablehomeservices.com/
Subdomain with errors https://jacksonville.remarkablehomeservices.com/

I have contacted theme developers as well. Just posting here to cover my bases. Thanks.
