Since you mention it seems to be related to Premium Templates, could you please send us an email at [support@wpovernight.com](https://wordpress.org/support/topic/fatal-error-division-by-zero/support@wpovernight.com?output_format=md) including your license key? We’ll then get working on resolving this ASAP! * Plugin Contributor [Ewout](https://wordpress.org/support/users/pomegranate/) * (@pomegranate) * [4 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-division-by-zero/#post-15344959) * > Is it safe to try and roll back to a previous version of the plugin, to see > if the templates still work there? * Yes, as a temporary solution you can certainly do that, you can download the previous version here on wordpress.org: [https://downloads.wordpress.org/plugin/woocommerce-pdf-invoices-packing-slips.2.12.1.zip](https://downloads.wordpress.org/plugin/woocommerce-pdf-invoices-packing-slips.2.12.1.zip) * Plugin Contributor [Ewout](https://wordpress.org/support/users/pomegranate/) * (@pomegranate) * [4 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-division-by-zero/#post-15345516) * This turned out to be a combination of customizer settings (no totals or columns for a specific document) and the PHP version (8.0+). * We have just released an update for the Premium Templates extension (2.17.0) addressing this issue so that it can be used with the latest version of the free plugin.
