Frequently Asked Questions

Common questions about Back In Stock Notifier for WooCommerce | WooCommerce Waitlist Pro

Actually, we sync and send the email to your subscribers in a background process, so server crashes or timeouts are ignored when using our plugin. This ensures a 99.99% success rate for sent emails.

You can do this by using the native way of WordPress. Go to Admin Dashboard -> Tools -> Export -> Subscribers -> Download Export File (xml). Later, you can import that data into your new site by visiting Admin Dashboard -> Tools -> Import -> Upload Downloaded XML file and Finish Import. Now you've successfully migrated subscribers' data.

We use one layer of security to our ajax request which is WP Nonce, but due to caching mechanism from third party plugins/hosting this security nonce also cached which cause this error "something went wrong, please try again after some time", some cases by setting up cache timeout in plugin settings reduce this kind of issue.

We added new techniques in version 2.0 to avoid the Something Went Wrong Error. If your site has encountered such issues, we suggest you try the below steps to get rid of the Something Went Wrong Error. Switch to the WordPress REST API Route: Go to Admin Dashboard -> Instock Notifier -> Settings -> Troubleshoot Settings Section -> Frontend Subscribe Form Submission. One is WordPress AJAX (default) and the other is WordPress REST API Route. Try changing that option to "WordPress REST API Route" and checking it out (purge your cache and check it out). Google reCAPTCHA: Consider using Google reCAPTCHA v2 or v3. You will need a Site Key and a Secret Key for this. (Go to Admin Dashboard -> Instock Notifier -> Settings -> Bot Protection -> Bot Protection through -> Google reCAPTCHA -> 1. Enable Google reCAPTCHA in Subscribe Form : Enable 2. Select Google reCAPTCHA version -> v2/v3. Enter the Site Key and Secret Key corresponding to the selected version for proper operation.) Turnstile: Consider using Turnstile as an additional bot protection option. You will need a Site Key and a Secret Key for this. Go to Admin Dashboard -> Instock Notifier -> Settings -> Bot Protection -> Bot Protection through -> Turnstile -> Enable Turnstile in Subscribe Form (Enable) -> Turnstile Site Key -> Turnstile Secret Key.

Create a folder inside your current theme with the name "back-in-stock-notifier-for-woocommerce." For example: wordpress -> wp-content -> themes -> storefront/(your theme) -> back-in-stock-notifier-for-woocommerce. Go to our plugin folder, then inside, find the "templates" folder. (wordpress -> wp-content -> plugins -> back-in-stock-notifier-for-woocommerce -> templates -> default-form.php) Open the "templates" folder and copy the file with the name "default-form.php" from that folder. Now, paste the copied file inside your theme under the folder with the name "back-in-stock-notifier-for-woocommerce" (step 1). That's all. Now, you've successfully loaded the template from your theme, and you can edit it however you want.

Not all site owners manage stock within the website; some of them manage their stock through third-party inventory management. The problem with our plugin is that Automatic Instock Email is not triggered/detected because some third-party software directly updates the stock in the database. From v2.4, we methodologically implemented support for Third-party stock management to send our Automatic Instock Email. Do the following: Go to Admin Dashboard -> Instock Notifier -> Settings -> Troubleshoot Section -> Enable this option if you have updated the stock from a third-party inventory plugin. Enable that checkbox option and save changes. Now we check the product every five minutes to trigger our Automatic Instock Email when the stock status becomes "In Stock."

Our plugin syncs with WordPress users who subscribe to our plugin. In some cases, an email id can be added without subscriptions (like cart abandonment, checkout page, etc.) by website owners. To check such emails, you can go to Admin Dashboard -> Users -> Add any data you want. For example, custom text.

If your product is in stock and your subscribers didn't get emails, do the following: 1. Go to Admin Dashboard -> Instock Notifier -> Settings. 2. Go to the Troubleshoot Section. 3. Set "Enable to send Instock Email after 'X' time when stock becomes Instock" to something like 5 minutes. 4. Save Changes.

Without an SMTP plugin, WordPress sends email through the server's PHP mail() function. The server accepts the email (which is why the status says sent), but many servers cannot actually deliver it, or the email lands in spam. To fix this, install and configure an SMTP plugin such as WP Mail SMTP or FluentSMTP so emails are sent through a real mail service. You can verify delivery from Admin Dashboard -> Instock Notifier -> Status -> Test Email.

From Version 2.0, we added support for REST API, which allows you to create/update/get/delete subscribers. For this, you need Consumer Key and Consumer Secret.
