I manually downgraded PHP version in Siteground to 8.1.29 but that didn't resolve it. I'm hoping the issue can be resolved with a fix to the theme and not with a manually updating the code on specific lines below. 

WordPress version 6.6.2
Active theme: TheFox (version 3.4.5)
Current plugin:  (version )
PHP version 8.2.24
