Should this work with Zencart v 1.5.6 and PHP v8.0?

I ran it through a PHP tester and got the following:
Warning: require_once(): open_basedir restriction in effect. File(includes/application_top.php) is not within the allowed path(s): (/var/tmp/) in /tmp/31yrgpkae1ktco5pkq/tester.php on line 17 Warning: require_once(includes/application_top.php): Failed to open stream: Operation not permitted in /tmp/31yrgpkae1ktco5pkq/tester.php on line 17 Fatal error: Uncaught Error: Failed opening required 'includes/application_top.php' (include_path='.:') in /tmp/31yrgpkae1ktco5pkq/tester.php:17 Stack trace: #0 {main} thrown in /tmp/31yrgpkae1ktco5pkq/tester.php on line 17
