ERR_TOO_MANY_REDIRECTS is a common error caused by an infinite redirect loop, where a user is automatically redirected from one URL to another, and then back to the original URL, resulting in an endless loop of redirects. This issue can occur due to several reasons, including: (1) duplicate or conflicting configuration files, (2) misconfigured proxy servers or load balancers, (3) incorrect settings on email or contact form plugins, or (4) issues with website caching or browser cookies.
To resolve this error, you should investigate the cause of the infinite redirect loop and address it accordingly. For email or contact form functionality specifically:
1. Check the email sending settings: Verify that the email sending settings are configured correctly, including the SMTP server, port, username, and password. Make sure that these settings match the website's requirements.
2. Inspect the contact form configuration: Ensure that the contact form plugin or script is properly configured, with the correct URL, form action, and method (e.g., GET or POST).
3. Verify email server logs: Check the email server logs to identify any errors or issues that might be causing the infinite redirect loop.
If you've checked all of these potential causes and still encounter the ERR_TOO_MANY_REDIRECTS error, consider reaching out to the website's hosting provider or a technical support specialist for further assistance.
