# Troubleshooting the “Error, Unable to access library database, please try re-syncing” error on the Kadence Blocks Design Library

You may see the following error when opening the Kadence Design Library: **“Error, Unable to access library database, please try re-syncing.”**  
  
This indicates that your site is unable to connect to Kadence’s Design Library API or is unable to store the library data locally. In most cases, this is caused by a server, security, or connection-related issue rather than a bug in Kadence.

**Why This Happens**

The Kadence Design Library relies on:

- The WordPress REST API
- Outbound HTTPS connections from your server

If any of these are blocked or misconfigured, the library cannot sync and show items properly.

**Step-by-Step Solutions**

Below are some common solutions that can help resolve the error entirely.

**Step 1: Re-sync the Design Library**

This should always be the first troubleshooting step.

1. Open the **Kadence Design Library**.
2. In the Design Library modal, click the *Sync with cloud* **refresh** **icon** in the **top-right corner**.

**Step 2: Check Whether the REST API Is Blocked**

Kadence uses the WordPress REST API to sync and download Design Library items. If REST API requests are blocked, the library cannot connect.   
  
**Common causes include:**

- Security plugins
- Hosting firewalls
- ModSecurity rules at the server level

**What to do:**

- Temporarily disable any active security plugins.
- Re-sync the Design Library.
- If the issue resolves, adjust your security plugin or firewall rules to allow REST API requests.

**Step 3: Confirm Your Server Allows Outbound HTTPS Requests**

Your server must be able to make outbound HTTPS connections to Kadence’s servers.  
  
**Common causes include:**

- cURL is not enabled or installed
- Outbound connections are blocked by the hosting provider
- SSL certificate issues on the server

**What to do:**

1. Go to **Dashboard > Tools > Site Health > Info**.
2. Open the **Server** tab.
3. Confirm that **cURL** is listed and enabled.

If cURL is missing or errors are reported:

- Contact your hosting provider and ask them to: 
    - Enable or install cURL
    - Allow outbound HTTPS requests from your server

Most hosts can confirm or adjust these settings quickly.

**Next Steps**

If you have completed all steps above and the error still appears:

- Provide your hosting provider with the exact error message
- Ask them to check for blocked REST API or outbound HTTPS requests

Once server-level restrictions are resolved, the Kadence Design Library should sync and work without errors.
