WordPress 403 Forbidden: Causes, Fixes, and Prevention Tips

WordPress 403 Forbidden: Causes, Fixes, and Prevention Tips

Imagine you’re in the middle of working on your WordPress site and suddenly—bam! WordPress 403 Forbidden error appears on your screen. It’s like running into a locked door with no way around it. Annoying, right? But don’t worry; this error is more common than you think and the fixes are often easier than they seem.

A 403 Forbidden error occurs when your server refuses to let you access a certain resource. This could be due to incorrect file permissions, faulty plugins, security settings, or hotlink protection. It can show up as “Access Denied” or “You don’t have permission to view this page” and affects both admin tasks and visitor experience. So here’s to it.

What Is the 403 Forbidden Error?

The 403 Forbidden error is an HTTP status code that means your server understands your request but refuses to let you access the page you’re trying to get to. Think of it as trying to open a door you know exists but being denied entry despite having the key. It’s a server-side communication issue that signals restricted access.

Common variations of the message include:

• “403 Forbidden – Access Denied.”
• “You don’t have permission to access this page.”
• “HTTP Error 403 – Forbidden.”

This error typically arises due to issues like misconfigured file permissions, incorrect .htaccess rules, blocked IPs, or certain security plugins overstepping their bounds. Sometimes it’s just a wrong URL and sometimes it’s hotlink protection misconfigured.

Annoying as it is, 403 is not a dead end. It’s a clear sign that something is preventing the server and your browser from talking to each other. With a methodical approach, such as checking file permissions or deactivating plugins, you can figure out and fix the problem.

Knowing the root cause of the 403 Forbidden error is important not only to fix it but also to prevent future interruptions to your WordPress site.

Why does 403 Forbidden Error Happen?

403 Forbidden error happens when your server blocks access to specific resources due to configuration issues. Here’s a breakdown:

1. Incorrect File Permissions

File permissions dictate who can read, write, or execute files on your server. If permissions are misconfigured, your server will deny access to important files or directories and you’ll get a 403 Forbidden error. For example, if your directories lack the correct 755 permission or files aren’t set to 644, WordPress might struggle to load resources. These overly restrictive settings prevent public or administrative access. Conversely, permissions that are too loose, such as 777, might activate hosting security mechanisms to block access due to potential vulnerabilities.

Solution: To resolve this, use a File Manager or an FTP client to adjust permissions. Set directories to 755 and files to 644. Avoid granting excessive privileges as they increase security risks. Hosting providers often provide tools to diagnose and adjust these settings, ensuring compatibility with your server environment.

2. Plugins

Plugins add functionality but a poorly coded or incompatible plugin can cause mayhem. Security plugins might mistake legitimate user actions for malicious activity block access and trigger the 403 error. Plugin conflicts can happen when two plugins try to modify the same settings or resources and cause unexpected errors. Outdated plugins or plugins that are not compatible with the current WordPress version will make these problems worse.

Solution: Deactivate all plugins and see if the site works. If it does, reactivate plugins one by one to find the culprit. Make sure all plugins are updated to the latest version and from trusted developers. If needed, replace the problematic plugin with a better one.

3. Corrupted .htaccess File

The .htaccess file is where you manage server rules like redirects, caching, and access restrictions. Even a small mistake can block resource access. For example, bad rewrite rules or leftover code from uninstalled plugins can break the file and give you a 403. Plugin updates or changes to WordPress settings can corrupt this file unintentionally.

Solution: Rename the .htaccess file via FTP or File Manager (e.g. .htaccess-old). This will disable the current file. Then log in to your WordPress dashboard, go to Settings > Permalinks, and save changes to regenerate a new .htaccess file. Check for errors and manually add back any customizations.

4. Hotlink Protection

Hotlink protection is a great security feature to stop other sites from embedding your media files (images or videos) on their site without permission. However, misconfigured rules can block legitimate requests from your own site or users. This happens when the protection is too strict or essential domains (your CDN or subdomains) are not allowlisted.

Solution: Check your hotlink protection settings in your hosting or CDN control panel. Allowlist your site’s domain and any subdomains. Make sure your settings can differentiate between legitimate requests and hotlinking attempts. 

5. DNS Configuration

The Domain Name System (DNS) translates your domain name into the server’s IP address. Misconfigured DNS records (like A records or outdated name servers) can stop your browser from connecting to the right server. This miscommunication can result in a 403 Forbidden error.

Solution: Check your DNS with your domain registrar or hosting provider. Make sure your A record points to the right server IP. Update name servers if needed and allow 48 hours for DNS to propagate. Tools like WhatsMyDNS can help you check if your settings are live worldwide.

6. Blocked IPs

Some hosting providers or security tools block IP addresses they consider suspicious. While this protects against attacks, it can block legitimate users or even site admins. This can happen with shared IP addresses or overzealous security settings.

Solution: Check your server’s access logs or security plugin settings to find the blocked IPs. allowlist your IP or the blocked IPs of legitimate users. If using a security plugin, adjust the settings to minimize false positives while still being secure.

7. Ownership Issues

Ownership issues occur when server resources are not assigned to the right user or group. For example, if your web server runs as www-data but the files are owned by another user, the server will deny access and give a 403. These happen during manual file uploads or server migrations.

Solution: Use the chown command via SSH to fix ownership. Set ownership to match your web server’s user. 

For example:

Sudo chown -R www-data:www-data /path/to/wordpress

If SSH isn’t an option, contact your hosting provider for assistance.

• Clear your browser’s cache and cookies:
• Chrome: Settings > Privacy and Security > Clear Browsing Data.
• Firefox: Options > Privacy & Security > Cookies and Site Data.
• Then restart your browser and try again.

3. Fix File Permissions

Why: File permissions might be set incorrectly restricting access to files or directories and causing a 403 error.

• Go to your WordPress files via FTP or cPanel file manager.
• Set permissions:
• Folders: 755 (owner: read, write, execute; others: read, execute)
• Files: 644 (owner: read, write; others: read)

• Rename to plugins_disabled.
• See if the error is gone. If so, rename back to plugins and activate plugins in the dashboard one by one to find the problem.

6. Turn off Hotlink Protection

Why: Hotlink protection settings in your control panel can block legitimate users or resources.

What to do:

• Log in to your account.
• Go to Hotlink Protection.
• Turn off or adjust to allow legitimate resources and users.
