 * Im getting this error on some computers/phones (not all though) when people are
   trying to access the site:
 * Fatal error: Cannot declare class WbsVendors\Dgm\Shengine\Calculators\ConstantCalculator,
   because the name is already in use in /home/customer/www/primalraw.co.uk/public_html/
   wp-content/plugins/weight-based-shipping-for-woocommerce/server/vendor/dangoodman/
   shengine/src/Calculators/ConstantCalculator.php on line 9
    There has been a critical
   error on your website.
 * Would anyone be able to assist me with this please?

 * I think I have fixed the error, I deleted the plugin and then added it in again
   and it seems ok
