# Continuous loading

If you visit the WooCommerce Email Customizer and face "An error occurred" notice showing up on the bottom-right of the screen, here's how to troubleshoot it.

### What causes the issue

Most likely, it is often caused by some third-party functions.

For instance, if you have the [Smart Coupons](https://woocommerce.com/products/smart-coupons/) latest version 7.11, it may add some new functions that are not yet recognized by our YayMail Addon. As a result, the email customizer screen cannot load.

### How to fix it

In this case, we would need to reproduce the issue. Then we will be able to look into those third-party plugin versions to look for their new functions.

Here are the actions you need to take:

* Send us the screenshot or the list of activated plugins on your site where the issue is happening.
* Share the third-party plugins' ZIP files so we can reproduce the environment.
* If necessary, please create a temporary admin account for us, or share a [Temporary Login Without Password](https://wordpress.org/plugins/temporary-login-without-password/).

Once our tech team finishes supporting those new functions, we will release the fix in YayMail Addons for you!
