I solved it using PHP 7.4.23. Specifically, It seems that there is a minimum and a MAXIMUM version of PHP to work with, i.e., PHP 8.0.010 (and higher) is the problem. Specifically:
– with PHP 7.133 the website works
– with PHP 7.2.34 the website works
– with PHP 7.3.30 the website works
– with PHP 7.4.23 the website works
– with PHP 8.0.010 “Warning: The magic method Vc_Manager::__wakeup() must have public visibility in /home/customer/www/tracemaker.com/public_html/wp-content/plugins/js_composer/js_composer.php on line 221”
