I just installed your plugin as it does what i exactly need.
I was checking how it works so i added incremental quantity to product and proceed to checkout then i went back to same product page decrease the quantity and clicked add to cart button and BOOM it gave error message and then site goes blank with just 'error' showing on screen.
Warning: Division by zero in /home/*********/wp-content/plugins/woocommerce-incremental-product-quantities/product-quantity-validations.php on line 137 Warning: Cannot modify header information - headers already sent by (output started at /home/*********/wp-content/plugins/woocommerce-incremental-product-quantities/product-quantity-validations.php:137) in /home/********/wp-includes/pluggable.php on line 876
Please take a look at error message and if possible please fix this error asap because this plugin was the only reason that i didn't switch to another shopping cart.
Thanks in advance.
