Incompatibility – W3 Total Cache

    Hello.

    When using the plugins “W3 Total Cache” and “Back In Stock Notifier for WooCommerce”, we have detected an incompatibility between them.

    When the cache is enabled, some of the random notification emails sent when a product is back in stock are missing certain data in the message — for example, the recipient’s full name may be missing. In short, we’re experiencing issues with email delivery.

    When the cache is disabled, everything works correctly. Could you please check this?

    Thank you!

    Hi there,

    Thank you for the detailed report.

    Our Back In Stock Notifier emails use WooCommerce’s default email header and footer templates, and all dynamic data (name, email, product, variation, etc.) is generated fresh each time the email is triggered. Because of that, our plugin itself does not cache or reuse any email content.

    However, W3 Total Cache can still interfere if:

    • Page cache or object cache stores parts of the WooCommerce email template, or
    • Any caching layer accidentally captures dynamic hooks used by WooCommerce email generation.

    To fix this, please try the following:

    1. Exclude WooCommerce email templates and our plugin’s dynamic hooks from W3 Total Cache.
      — Exclude /wp-content/plugins/woocommerce/templates/emails/*
      — Exclude our plugin folder /wp-content/plugins/back-in-stock-notifier/*
    2. Disable Object Cache temporarily and test again. Object Caching is the most common cause of dynamic email data missing.
    3. Purge all caches (page, object, database, CDN if used).

    If the issue persists, please share:

    • A screenshot of your cache configuration
    • Which caching layers are enabled (page cache, object cache, database cache, fragment cache, etc.)

    We’ll be happy to help you get this resolved.

    Thanks
