 * Hi [@fhgfhf](https://wordpress.org/support/users/fhgfhf/)
 * I hope you’re well, thanks for question!

 * This kind of problem is usually caused by a conflict with your theme or with 
   another plugin.
      The best way to determine this is to:
    - Temporarily switch your theme to [Storefront](https://www.woocommerce.com/storefront/)
    - Disable all plugins except for WooCommerce
    - Repeat the action that is causing the problem
 * If you’re not seeing 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/)`
 * I hope that helps!
 * Let me know how it goes!

 * It’s a production site so i need to clone it etc
    If you’re sure that it’s caused
   by another plugin or theme i’ll mark it as solved <3
 * Or you can add a tiny little if(ACTIVE_TASK_TRANSIENT) O:)

 * Such issues generally occur due to theme/plugin conflict. If you want to be sure
   about it, I would suggest performing the conflict test on your clone site by 
   following the instructions suggested by [@solstudioim](https://wordpress.org/support/users/solstudioim/).
 * You can let us know the result once you are done with the conflict test.
 * Thank you!
