Title: Coupon Code Problem – Division by Zero Last modified: August 30, 2016 --- # Coupon Code Problem – Division by Zero * Resolved [SimpleBeadPatterns](https://wordpress.org/support/users/simplebeadpatterns/) * (@simplebeadpatterns) * [10 years, 10 months ago](https://wordpress.org/support/topic/coupon-code-problem-division-by-zero/) * Hi, * A customer got this error when adding a coupon to their shopping cart. When I tried it myself, it worked. Any ideas what this error means? * Warning: Division by zero in …/wp-content/plugins/jigoshop/classes/jigoshop_cart. class.php on line 592 * When researching this error, I found one post saying that someone needed to update their Jigoshop Premium Shipping, but I am not using Premium Shipping – I am using Table Rate Shipping that I purchased from Jigoshop. * Any help would be greatly appreciated (we just put out a big ad!) * Thanks! * [https://wordpress.org/plugins/jigoshop/](https://wordpress.org/plugins/jigoshop/) Viewing 13 replies - 1 through 13 (of 13 total) * Thread Starter [SimpleBeadPatterns](https://wordpress.org/support/users/simplebeadpatterns/) * (@simplebeadpatterns) * [10 years, 10 months ago](https://wordpress.org/support/topic/coupon-code-problem-division-by-zero/#post-6306203) * This is what is on line 592 of my jigoshop_cart.class.php: * $discounts += self::$tax->calc_tax($coupon[‘amount’] * self::$price_per_tax_class_ex_tax[ $tax_class]/($total_tax_part*100), $rate, false); * Thank you! * Thread Starter [SimpleBeadPatterns](https://wordpress.org/support/users/simplebeadpatterns/) * (@simplebeadpatterns) * [10 years, 10 months ago](https://wordpress.org/support/topic/coupon-code-problem-division-by-zero/#post-6306206) * I am now getting the error myself. The error is happening when it is an in-state purchase needing to charge tax. The error does not happen if tax does not need to be charged. If I turn tax off, then it works fine. So, this error is only happening when someone is making a purchase where tax is being charged. Please help asap! * Thank you. * [Jigoshop Support-Vasili](https://wordpress.org/support/users/vasiliborbis/) * (@vasiliborbis) * [10 years, 10 months ago](https://wordpress.org/support/topic/coupon-code-problem-division-by-zero/#post-6306268) * Hi SimpleBeadPatterns, * Try to disable other shipping methods and see if it works. * Thread Starter [SimpleBeadPatterns](https://wordpress.org/support/users/simplebeadpatterns/) * (@simplebeadpatterns) * [10 years, 10 months ago](https://wordpress.org/support/topic/coupon-code-problem-division-by-zero/#post-6306322) * Thank you for your response. Shipping is not enabled on one of my websites because it is downloadable products only. On a different website that I sell physical products on, I have the table rate shipping extension. The shipping is being calculated correctly for different countries on that website, but for some reason I cannot find the table rate shipping settings under shipping on the Jigoshop settings page. I edited these settings before, but I can’t locate them now. I thought those settings used to be displayed on the shipping page. Did something change so that the table rate shipping settings are displayed somewhere else? * So, one website has no shipping enabled and another website is table rate shipping only. I am getting this error on both of these sites when someone who is being charged tax uses a coupon code. * Thank you for your help. * [Jigoshop Support-Vasili](https://wordpress.org/support/users/vasiliborbis/) * (@vasiliborbis) * [10 years, 10 months ago](https://wordpress.org/support/topic/coupon-code-problem-division-by-zero/#post-6306377) * Hi SimpleBeadPatterns, * Could you provide please your system info? Also i’ve tested the table rate shipping on my web site and it’s working fine (I Also upplied coupons) * If you’r not seeing the table rate shipping in Jigoshop shipping settings try to deactivate and activate again the plugin. * Thread Starter [SimpleBeadPatterns](https://wordpress.org/support/users/simplebeadpatterns/) * (@simplebeadpatterns) * [10 years, 10 months ago](https://wordpress.org/support/topic/coupon-code-problem-division-by-zero/#post-6306396) * I tried disabling the table rate shipping plugin and then re-enabling it and I still can’t see the settings on the Jigoshop shipping page. * Here is the system info for my downloadable products website. I also included the system info for my physical products website. I am having the tax problem on both websites. * WordPress Environment Home URL: [?] [http://simplebeadpatterns.com](http://simplebeadpatterns.com) Site URL: [?] [http://simplebeadpatterns.com](http://simplebeadpatterns.com) Jigoshop Version: [?] 1.17.4 Jigoshop Database Version: [?] 1503180 Log Directory Writable: [?] ✕ To allow logging, make …wp-content/uploads/jigoshop-logs/ writable or define a custom JIGOSHOP_LOG_DIR.

In order to instal this new version of the plugin, I had to delete the plugin’s folder because it would not let me replace it with the new version of the Table Rate Shipping plugin (or I was not doing it right). When I uploaded the new version of the plugin, I had to activate it and it took away one of my available license activations (I have a 5 site license). How do I update my other websites with the new version of the plugin without using up my licenses? Also, are you able to restore the one license I just used on my SimpleBeadPatterns.com website when trying to upload the new version? (I had 4 licenses – now I have 3). * I updated my Jigoshop plugin to 1.17.7. I am still getting the Division by Zero error. I also tried disabling the Table Rate Shipping plugin and I still got the same error. * Thank you for your help! * Plugin Author [Jigoshop Support – Eric](https://wordpress.org/support/users/jigoshop-support/) * (@jigoshop-support) * [10 years, 10 months ago](https://wordpress.org/support/topic/coupon-code-problem-division-by-zero/#post-6306464) * Hi SimpleBeadPatterns * I have reset than one license for you. If the old version of the plugin is using licensing please try to deactivate the plugin first before deleting the plugin or it’s folder so save the number of activation. If you are replacing versions which don’t require a license key please let us know how many do you need to replace and we will increase the number of license activation. * We will also look further into that error * Thread Starter [SimpleBeadPatterns](https://wordpress.org/support/users/simplebeadpatterns/) * (@simplebeadpatterns) * [10 years, 10 months ago](https://wordpress.org/support/topic/coupon-code-problem-division-by-zero/#post-6306466) * Thank you so much for your help.

I really need to collect taxes from customers in my state, so I need to figure this out.
