If you do not see the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict. [You can find a more detailed explanation on how to do a conflict test here.](https://docs.woocommerce.com/document/how-to-test-for-conflicts/) As for uploading the system status report on the off chance the test is unavailing, then you can just post it directly here.

We can run a conflict test to verify this. I’d recommend cloning your site to a staging environment and performing the tests described on this [guide](https://woocommerce.com/document/how-to-test-for-conflicts/) without modifying your live site or impacting customers. Many hosts provide staging facilities, so it’s worth checking in with them. It’s also possible to do it using the free [WP Staging](https://wordpress.org/plugins/wp-staging/) plugin. * If this was caused by a third-party plugin present on your site, it would be best to reach out to the developers for further assistance here. * If this did not resolve the issue, please provide the **fatal error logs** (if any) under `WooCommerce > Status > Logs`. * Let us know how it goes! * Thread Starter [ripasolutions](https://wordpress.org/support/users/ripasolutions/) * (@ripasolutions) * [3 years, 4 months ago](https://wordpress.org/support/topic/error-when-adding-a-product-2/#post-16325078) * Now i know which plugin caused the problem.
