Infinite redirect loops and "Too Many Redirects" errors occur when a website continuously redirects users between different URLs without reaching a final destination. This issue can prevent users from accessing your site and negatively impact SEO and user experience. This guide explains the causes and provides step-by-step solutions to resolve the problem.

Common Causes of Infinite Redirect Loops

• Incorrect redirect rules in .htaccess, Nginx, or web server settings.
• Conflicting HTTPS and HTTP redirects.
• Misconfigured WordPress settings, plugins, or caching mechanisms.
• Cloudflare or CDN redirect conflicts.
• Incorrect domain or subdomain settings.

How to Identify Redirect Loop Issues

Before fixing the problem, it's essential to diagnose the root cause. Use the following methods:

• Browser Console: Check network requests (F12 → Network → Redirects).
• Online Redirect Checkers: Use tools like Redirect Checker to analyze redirect chains.
• Server Logs: Examine web server logs for excessive 301/302 redirects.
• Cloudflare Overview: If using Cloudflare, check the SSL/TLS settings for conflicts.

Fixing Redirect Loop Issues

1. Check WordPress URL Settings

For WordPress sites, incorrect "Site URL" and "Home URL" values can cause infinite redirects.

To fix it:

define('WP_HOME', 'https://yourwebsite.com'); 
define('WP_SITEURL', 'https://yourwebsite.com');

Alternatively, update the values in the WordPress database using phpMyAdmin:

UPDATE wp_options SET option_value = 'https://yourwebsite.com' WHERE option_name = 'home'; 
UPDATE wp_options SET option_value = 'https://yourwebsite.com' WHERE option_name = 'siteurl';

2. Fix .htaccess Redirect Rules (Apache)

Misconfigured .htaccess rules often cause redirect loops. Reset your .htaccess file by adding:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://yourwebsite.com/$1 [R=301,L]

3. Correct Nginx Redirect Rules

If you use Nginx, ensure there are no conflicting redirects in your server block:

server {
  listen 80;
  server_name yourwebsite.com;
  return 301 https://yourwebsite.com$request_uri;
}

4. Adjust Cloudflare SSL Settings

Cloudflare’s Flexible SSL setting can cause redirect loops. Change SSL/TLS settings to "Full" instead of "Flexible" in Cloudflare’s dashboard.

5. Disable Redirect Plugins or Conflicting Plugins

If you use WordPress, disable redirect-related plugins:

wp plugin deactivate redirection

Clear cache and test if the issue is resolved.

Final Steps

After applying fixes, clear browser cache and test using an incognito window. If the problem persists, check server logs for further debugging.
