Hi @disait,
when you add to cart something then it reloads the whole page again.
That’s not the default behavior of WooCommerce. 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
- Disable all plugins except for WooCommerce
- Repeat the action that is causing the problem
If you’re not seeing the same behavior after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated.
Reactivate the theme first and check again. Then, go on and 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/.
Please make sure you have a backup in place of your site and database. You could also consider using a service like Jetpack. If something goes wrong, it’s nice to know that you can restore your site to the previous state.
Thanks!
