What is the 403 Forbidden Error?

The 403 Forbidden error is an HTTP status code that indicates the server understands the client’s request but will not fulfill it.

The 403 Forbidden error typically occurs when the visitor or search engine crawler does not have the required permissions or security settings to access the resource. For example, a visitor may encounter this error when attempting to access a site’s admin area. 

Some sites may be configured to return a 404 Not Found error instead of 403 Forbidden to hide the fact that the page exists. If you are sure the page exists, you should look into your permissions and security settings. 

The 403 Forbidden error belongs to the 4xx series of HTTP status codes.

Causes of the 403 Forbidden Error

The 403 Forbidden error can be caused by several factors relating to permission, access control, and server configuration. Some common causes include:

  • Inadequate permission
  • Blocked IP address
  • Corrupted .htaccess file

1 Inadequate Permission

Servers typically include permissions indicating who can read, write, and execute the site’s files. If these permissions are not set correctly, the server may deny visitors and search engine crawlers access, resulting in a 403 error.

2 Blocked IP Address

Servers can be configured to block requests from specific IP addresses or IPs within a particular range. So visitors visiting the site from the blocked IP will encounter a 403 Forbidden error. 

IP addresses are typically blocked as a security measure to prevent unauthorized access and malicious activities. It is often used to block visitors from a country or region from accessing a site.

3 Corrupted .htaccess File

Errors, misconfigurations, and restrictions within the .htaccess file can corrupt or invalidate your files and block visitors from accessing resources they should normally be able to access.

While the specific issue would vary, incorrect rewrite rules, misconfigured authentication settings, and restrictions on certain directories would typically lead to the 403 error.

How to Fix the 403 Forbidden Error

The 403 Forbidden error could result from a variety of reasons. So, the appropriate solution depends on the cause. However, here are a few ways to fix the error.

1 Clear Your Browser Cache

The 403 Forbidden error may result from outdated or corrupted cached files on your browser. Your browser may have also cached an earlier 403 error response you encountered during your previous visit to the page.

You can rectify this by clearing your browser’s cache. This removes the saved files and forces your browser to fetch the latest version of the page.

After clearing the cache, restart your browser to ensure the change takes effect. This step helps eliminate residual issues that may prevent the page from loading correctly.

2 Set the Appropriate Permissions

You should ensure to set the appropriate permissions for your files and directories.

Permissions should be correctly configured to grant authorized users the necessary read, write, and execute rights while restricting access to unauthorized users.

It’s important to use the correct permission values. For example, directories typically have their permissions set to 755, while files are set to 644. You can change these settings using an FTP client or command-line tools like “chmod.”

3 Fix Your .htaccess File

The .htaccess file is critical for managing server behavior and access control. If your server runs on Apache, navigate to your site files and rename the .htaccess file. Then, check if the 403 error persists.

If the error persists, check the file for syntax errors and incorrect directives. If you do not find any errors or incorrect directives, consider deleting the .htaccess file and generating a new one from your content management system (CMS) or host.

However, make sure to save a copy of your .htaccess file to your device before deleting it.

4 Modify Your Server’s IP Restrictions

Some servers may have been configured to block certain IP addresses or a range of IP addresses from accessing their site.

However, legitimate users can sometimes be affected by these restrictions, causing them to encounter the 403 Forbidden error.

So, review your server’s access control settings and unblock the IP addresses you want to access your site. The access control settings may be located in your site’s .htaccess file, firewall rules, or server configuration files.

5 Specify the Correct Index Page

Web servers look around for your default index file to serve when a directory is accessed. This file is typically named index.html or index.php and contains the site’s homepage.

If this index file is missing or incorrectly named, the server may return a 403 error.

So, you should check your site files and ensure it contains an index file. If the file exists, you should confirm it is correctly named and located in the root directory or relevant subdirectory.

Additionally, ensure there are no restrictive permissions on the index file itself.

How to Prevent 403 Forbidden Errors

403 errors can make your site inaccessible to visitors and search engine crawlers. This could affect your SEO and user experience. To prevent such, you should follow the tips and best practices below to prevent 403 Forbidden errors. 

1 Review Your Server Permissions

Permissions should be configured using the principle of least privilege. That is, you should only grant the minimum necessary permissions to users or processes. 

This helps reduce the risk of accidental exposure of sensitive data or unauthorized modification of files.

2 Review Your .htaccess File

Regularly review your .htaccess file to ensure it does not contain misconfigurations or unnecessary restrictions. 

However, remember to backup the file before making changes and use tools or syntax checkers to validate its configuration.

3 Analyze Your IP Restrictions

Servers can be configured to block specific IP addresses or ranges to protect against malicious activity. However, incorrect settings can block valid users. 

Analyze access logs to identify and correct IP addresses that have been blocked unintentionally. You should also ensure that your IP restriction rules are up-to-date and accurately reflect your security policies.

4 Configure Your Index Files

Ensure that default index files are correctly named and placed in the appropriate directories. 

You may need to verify your server’s configuration to recognize the correct index file names. You should also ensure that the index file is properly maintained and accessible.

5 Secure Your Server Settings

Conduct regular audits of your server’s security settings to prevent blocking valid requests. Implementing robust access controls helps secure your server while allowing legitimate traffic. 

Use security best practices such as setting up firewalls, enabling SSL/TLS, and configuring proper authentication and authorization mechanisms.

6 Update Your Server Software

Keep your server software, including the operating system and web server applications, updated with the latest security patches. 

Outdated software can contain vulnerabilities that attackers can exploit, leading to access issues and potential 403 errors. 

7 Analyze Your Server Log

Web server logs provide valuable insights into the root causes of errors, helping you identify patterns and recurring issues. 

Analyze your web server logs regularly to detect and promptly address access problems. You may also use logging tools to generate reports and alerts for significant events.
