# AJAX execution failed. Please first verify your module configuration... - Amazon Marketplace Plus

You get an error like:

||| AJAX execution failed. Please first verify your module configuration...

or

||| You are currently connected with the following domain: (domain)... This differs from the one set in "Preferences > SEO & URLs": (configured domain)

---

## Main Cause

The **domain you’re using doesn’t match** the one set in **Preferences > SEO & URLs** in PrestaShop.

This triggers a **security restriction** in the browser (cross-domain request), which blocks the AJAX call.

---

## Example

* URL used to log in: `http://mystore.com/admin`  
* Configured domain in PrestaShop: `http://www.mystore.com/admin`

✅ **Solution**: Always use the **exact URL** configured in your shop settings.

---

## Other Possible Causes

### 1. Hosting Restrictions (e.g. OVH)

Some hosts block AJAX scripts by default.

➡ Follow their guide on file/folder permissions:

### 2. Store in Maintenance or Inaccessible

The module only works if the **front-office is live and accessible**.

➡ Disable maintenance mode or fix redirection issues.
