How to Fix 401 Unauthorized Access Error in WordPress

Seeing a “401 Unauthorized” error on your WordPress site? This status code means that the page or resource you’re trying to access requires proper authentication—but your request isn’t passing the required credentials.

Whether you’re locked out of your admin area, login page, or a protected file, this guide will walk you through the steps to fix it using WordPress and cPanel.

What Causes a 401 Unauthorized Error?

- Incorrect login credentials or session expired
- Password-protected directories via .htaccess
- Security plugins blocking requests
- Server or firewall settings (like mod_security)
- Expired API tokens or .htpasswd rules

Step-by-Step Guide to Fix It

1. Clear Browser Cache and Cookies

If you’ve recently changed credentials, your browser might still be using an outdated session.

- Clear your browser’s cache and cookies
- Try logging in again from a different browser or incognito mode

2. Disable Security Plugins Temporarily

Some security or firewall plugins can mistakenly trigger 401 errors.

- Log into cPanel > File Manager > public_html/wp-content/plugins
- Rename the folder of your security plugin (e.g., wordfence to wordfence_old)
- Try accessing the site again

3. Check .htaccess for Password Protection

If you’ve enabled directory protection in cPanel:

- Go to File Manager > public_html
- Look for an .htaccess file and a .htpasswd file
- Remove or comment out the following lines if present:

AuthType Basic
AuthName "Restricted Access"
AuthUserFile /home/youruser/.htpasswds/public_html/passwd
Require valid-user

- Save the file and refresh your site

4. Remove cPanel Directory Protection

- In cPanel, go to Files > Directory Privacy
- Click your protected folder (like /wp-admin or /)
- Uncheck “Password protect this directory”
- Save and test again

5. Check API Access (For Developers or External Tools)

If you’re seeing 401 errors when accessing APIs (e.g., REST API, WooCommerce, third-party apps):

- Ensure the API key or token is valid and active
- Check that it has the right permissions
- Renew or regenerate the token if needed

6. Check Hosting Security Settings

Your server’s firewall might be blocking legitimate requests.

- In cPanel, go to ModSecurity (under Security section)
- Disable it temporarily for your domain and test
- If that fixes the issue, adjust rules or contact support

7. Contact Your Hosting Provider

If none of the above resolves the issue, contact your web host and ask them to check server logs. They can help identify blocks caused by security rules or permission conflicts.

Final Thoughts

The 401 Unauthorized error in WordPress can be frustrating, but it's typically caused by security settings or misconfigured authentication. With access to cPanel and your WordPress files, you can resolve it quickly.
