    Hi there

    Hello,

    Thanks for reaching out!

    This sort of issue may be caused by a conflict with your theme or a plugin. In order to address it, I would start by suggesting that you create a staging site if you don’t have one yet. Using WP Staging you will be able to clone your site and troubleshoot without affecting your live site.

    Then, once you have the staging site, I would suggest you perform a conflict test:

    • change your theme to Storefront
    • disable all plugins except for WooCommerce
    • check if the problem persists

    Please let us know if the issue persists. If the issue is gone, then you can reactivate your theme and plugins one by one until you identify the culprit.

    Let us know how it goes!

    Hi there,

    Yeah, that worked.

    Luckily it was in the first 10th of the plugin.

    The following code caused in code snippets caused it:

    add_action( ‘woocommerce_after_add_to_cart_button’, ‘select_variations’, 5 );

    Thanks for letting us know.

    I’ll mark this thread as resolved now. If you have any further questions, I recommend creating a new thread.

    Best.
