ProPluginsLab

Hello,

Thank you for sharing your concerns. We understand the frustration you experienced and apologize for the inconvenience.

We have been in contact with you and are glad the issue has now been resolved.

For clarification, support is active and the plugin is maintained. The troubleshooting step regarding temporarily disabling other plugins was suggested as part of standard conflict testing, which can help identify the cause of issues in some cases.

We appreciate your patience and feedback.

Hello,

Thank you for reaching out.

The shortcode {product_thumbnail} is not supported in the email templates. This shortcode was not available in previous versions of the plugin either.

To display the product image in the email, please use the following shortcode:

{product_image}

Our email templates currently support these shortcodes:

{product_name}, {product_id}, {product_link}, {shopname}, {email_id}, {subscriber_email}, {cart_link}, {only_product_name}, {only_product_sku}, {product_price}, {product_image}, {subscriber_name}, {subscriber_phone}, {subscriber_firstname}, {subscriber_lastname}

If you replace {product_thumbnail} with {product_image}, the product image will appear correctly in the email.

Please let us know if you need any further assistance. We are happy to help.

Best regards.

Hi,

Thank you for the detailed explanation – that information is very helpful.

Based on your setup and the symptoms described, here are some important points and recommendations: 1. WP Engine & DISABLE_WP_CRON

WP Engine disables WP_CRON and replaces it with a server-side cron. This setup is generally compatible with the plugin.
The “WP_CRON was disabled” message shown on the Status page is informational only and does not indicate an error by itself, especially since other Action Scheduler jobs are running correctly. 2. How stock changes trigger notifications

Back-in-stock notifications are triggered when WooCommerce detects a product transitioning from out of stock → in stock using its standard stock hooks.

If stock is updated:

• Directly at the database level, or
• Via a custom or third-party stock synchronization process that bypasses WooCommerce hooks

then the restock event may not be detected, and no notification job will be created. 3. Troubleshoot option (important clarification)

There is a setting under Troubleshoot (Experimental):

Enable this option if you have updated the stock from a third-party inventory plugin

This option can be enabled even if you are not using a third-party inventory plugin.
It acts as a fallback mechanism in cases where the standard WooCommerce stock change hooks do not fire for various reasons.

When enabled, the plugin periodically checks stock changes and can trigger back-in-stock emails even if the default hook-based detection is missed. We recommend enabling this option in your case and testing again. 4. Action Scheduler behavior

When stock changes are detected correctly, a related scheduled action should be created to process notifications.
If no new action appears when a product is restocked, it strongly suggests that the stock change is not being picked up by WooCommerce itself.

As a test, please try manually changing a simple product’s stock status from Out of stock → In stock in the admin and check whether a new scheduled action is created. 5. cwg_as_action_job_klaviyo “no callback registered”

This message indicates that a scheduled action exists for an integration that is not currently active. It does not affect core back-in-stock email notifications and can safely be ignored if that integration is not in use.
Old or failed actions can also be cleared from WooCommerce → Status → Scheduled Actions. 6. Background Process Engine

For WP Engine and similar managed hosting environments, please ensure the Background Process Engine is set to:
WooCommerce Background Process

This is the recommended and most reliable option for queuing and processing notifications. 7. Third-party stock update cron recurrence

If stock updates are handled externally (or if the fallback option mentioned above is enabled), we recommend setting the Third-Party Stock Update Cron Recurrence to 5 minutes to avoid delays.
Please also ensure that WP Engine’s server-side cron is triggering correctly at that interval.

Thanks.

Hi,

Thank you for reaching out, and we sincerely apologize for the long delay.

Due to our internal processing, we unfortunately missed your ticket (#2627) submitted over a month ago regarding the Mailchimp Pro plugin. We completely understand how frustrating this must be, and we’re truly sorry for the inconvenience caused.

Hi there,

Thank you for reporting this.

We’ve already fixed this display issue in our latest version of the plugin. The subscriber count showing as “0” (even though subscribers are visible inside the list) was caused by a technical glitch, and it has been resolved.

Please update to the latest version of the Back In Stock Notifier plugin and check again – the subscriber count will now display correctly in the Products list.

If you still see the issue after updating, please let us know and we’ll assist you further.

Thanks.

Hello there,

Good Day!

Our plugin supports Simple and Variable Products (including each variation) by default, so the subscribe form should appear when a specific variation is Out of Stock. If it’s not showing for that variation, it usually happens due to either: Theme or custom CSS hiding the variation’s “Out of Stock” wrapper, which prevents the form from loading, or A conflict with another plugin that modifies variation behaviour. To help you quickly, could you please share your product page URL? We’ll check it immediately and get this resolved for you.

Thanks.
