Fixed it in Cpanel – updated PHP version
Actually – issue with host. Site running an old version of PHP even though Cpanel and their admin says 7.4

Hi – I think its the theme or platform.
Turned on debugging
Fatal error: Cannot use BigCommerce\Customizer\Sections\Product_Single as Product_Single because the name is already in use in /home/eightli/loopyard.com/wp-content/plugins/bigcommerce/src/BigCommerce/Templates/Fallback_Image.php on line 9
used same theme here / different host here though and it works fine
