Fatal Error in version 1.5.9.3

Hi, i’m getting the following error:
PHP Fatal error: Uncaught Error:
Call to undefined method WPH_functions::get_site_module_saved_value() in /var/www/html/wp-content/plugins/wp-hide-security-enhancer/include/wph.class.php:617

This happens when trying to respond to a ?wc-api request with json/xml-rpc enabled

The entire stacktrace:
PHP Fatal error: Uncaught Error: Call to undefined method WPH_functions::get_site_module_saved_value() in
/var/www/html/wp-content/plugins/wp-hide-security-enhancer/include/wph.class.php:617

I couldn’t find the function get_module_item_setting defined anywhere. Anyone has any idea of what is going on here?

Thanks,
