I looked into your System Status Report (SSR) and I think the plugin Product Designer by PickPlugins could be the reason for this issue. Can you please deactivate this plugin and try again? * The reason is that our plugin uses the global `$post` to fetch the product data using `wc_get_product`. The error that you are facing is thrown only when the global `$post` object is overridden or set incorrectly. * This could happen when a third-party plugin overrides the `$post` object. From your SSR, the `Product Designer by PickPlugins` plugin could be the one doing that. * If deactivating `Product Designer` does not work, I’d recommend performing conflict testing which is to de-activate all other plugins except `WooCommerce` and `Facebook for WooCommerce` and switch the theme to WooCommerce’s default `Storefront` theme. * Let us know how this goes. * Thread Starter [faehrliebe](https://wordpress.org/support/users/faehrliebe/) * (@faehrliebe) * [3 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-uncaught-typeerror-20/#post-16435100) * Hi [@kaderibrahim](https://wordpress.org/support/users/kaderibrahim/) , thanks for your support! now it works fine! * [xue28 (woo-hc)](https://wordpress.org/support/users/xue28/) * (@xue28) * [3 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-uncaught-typeerror-20/#post-16435473) * Hi [@faehrliebe](https://wordpress.org/support/users/faehrliebe/) * You are most welcome and we’re glad that worked! 🙂 * Since this is a third-party plugin ([Product Designer by PickPlugins](https://pickplugins.com/item/product-designer/)) which we don’t provide support for (please see our [Support Policy](https://woocommerce.com/support-policy/)), it would be best to reach out to the plugin’s developers for further assistance here. * [https://pickplugins.com/support/](https://pickplugins.com/support/) * I will be marking this thread as resolved.
