What causes a 401 status code?

A 401 status code is caused by a lack of valid authentication credentials for the requested resource. This can occur if the user provides incorrect or expired credentials, the authentication credentials are missing, or the authentication method used is not supported by the server.

What is the difference between a 401 status code and a 404 status code?

A 401 status code indicates that the client lacks valid authentication credentials for the requested resource, while a 404 status code indicates that the server could not find the requested resource. In other words, a 401 status code means that the server knows the requested resource exists, but the client is not authorized to access it. A 404 status code means that the server does not know the requested resource exists.

What is the difference between a 401 status code and a 403 status code?

A 401 status code indicates that the client lacks valid authentication credentials for the requested resource, while a 403 status code indicates that the client has valid authentication credentials but is not authorized to access the requested resource.

Does a 401 status code affect SEO?

A 401 status code does not affect search engine optimization (SEO) directly.

However, it can impact user experience if the user is unable to access the requested resource. If the resource is important for SEO purposes, such as a login page or a page with valuable content, a 401 status code can negatively impact SEO indirectly.

How to fix ‘You are not authorized to view this page (403 error)’ in WordPress sites

A common error that happens when you try to login to the WordPress admin section is ‘You are not authorized to view this page (403 error)’.

This 403 error gets displayed instead of the WordPress admin dashboard, after successful authentication using the admin login credentials.

What causes ‘You are not authorized to view this page (403 error)’

WordPress is programmed in PHP and the default page that loads once a admin user login, is the ‘index.php’ file.

The ‘Directory Index’ directive of a webserver is used to set the list of files to look for, when the client requests an index of the directory in a website.

But if the webserver where the WordPress site is hosted doesn’t support ‘index.php’ in ‘Directory Index’, this 403 error would show up instead of the index page.

‘You are not authorized to view this page (403 error)’ in WordPress

In Apache webservers, ‘index.php’ would be already configured in ‘Directory Index’ section in the webserver configuration file. So, the 403 error is not seen much in Apache servers.

But in Windows servers, the ‘Default documents’ are used to configure ‘Directory Index’ for websites. The default documents that are enabled by default are:

When a page request comes from a website, the IIS webserver checks the file names listed in this ‘Default Documents’ and sends it to the browser.

Since ‘index.php’ is not enabled as a Default document in Windows IIS server, this 403 error in WordPress is often encountered in Windows servers.

How to fix ‘You are not authorized to view this page (403 error)’

To update the Default Documents of your website to include ‘index.php’ file, follow these steps in Windows webserver:

Open IIS Manager.
Right-click the Web site for which you’ve installed WordPress and then click ‘ Properties’ .
Click the ‘ Documents’ tab. Click to select the ‘ Enable Default Document’ check box.
Click Add . In the Default Document Name box, type the name of the default document (index.php) that you want to add and then click OK .
Refresh your browser or login again to http://domainname.com/wp-admin/

To enable ‘Default Documents’ for a website, another option is to make sure that the following entries are present in the web.config file in the root of the website.

web.config file entries to set index.php for WordPress

Now we have enabled processing of index.php file by the web server, and your WordPress admin dashboard would be displayed fine without any errors.

If you are on a Linux server, to ensure that index.php is returned by default for a directory, create an .htaccess file in that directory and add this line to it:

DirectoryIndex index.php index.html

403 error can also happen due to a corrupt ‘.htaccess’ file or wrong file permissions. To fix this, ensure that the .htaccess and index.php files have 644 permissions.

In short

403 error can show in WordPress during installation or when trying to login as user. The error message can vary with server, some showing ‘Access Denied’.

Certain WordPress plugins or security plugins in the server can also lead to 403 errors. In such cases, examining the error logs and each plugin is relevant to resolve this error.
