From my web host support: "Hello, Daniel,
I understand your concern regarding website functionality.
I have checked the website https://startree.tv/ and was able to duplicate the reported issue. Currently, PHP version 7.4 is set for your account. It looks like the script you are using is not compatible with PHP version 7.4. This is the reason website is showing error message. It is working fine with PHP version 7.3. You can switch the PHP version to 7.3"
