A website lead form is a tool that captures visitor information on your website, but if it's not working correctly, it can prevent potential customers from getting in touch with you. To identify the issue, check if visitors are filling out the form but not receiving a response or if the form is not visible on your website. This guide will help you troubleshoot and fix the problem.

What is a website lead form and why is it not working?

A website lead form is an online tool that allows visitors to submit their contact information, such as name, email address, and phone number, in exchange for a service, product, or more information about your business. Its main purpose is to capture potential leads and convert them into customers.

A lead form typically consists of a few fields, such as name, email, phone number, and message. It may also include a submit button that triggers an action, like sending an email or adding the lead to a database.

If your website lead form is not working, it can be frustrating and may be costing you potential customers. Here are some signs that indicate a lead form issue:

  • The form is not visible on your website
  • The form is visible, but the submit button is not working
  • The form is submitting, but the data is not being received or stored properly
  • The form is not sending emails or notifications to your team
  • The form is not displaying any error messages when something goes wrong

Common causes of a non-working website lead form

Incorrect form settings can cause a website lead form to malfunction. This includes issues with form fields, submission buttons, and validation rules. Ensure that all required fields are correctly set up and that the form is configured to send submissions to the intended email or database.

Plugin or theme issues

A plugin or theme conflict can also prevent a website lead form from working properly. This can be due to outdated or incompatible plugins, or theme settings that override the form's functionality. Check for any plugin or theme updates and consider deactivating them one by one to identify the cause.

  • A server error can occur due to high traffic, server overload, or incorrect server settings.
  • A misconfigured email address or SMTP settings can prevent the form from sending submissions.
  • A conflict with other website elements, such as JavaScript or CSS, can also cause issues with the form.
  • A security certificate issue, such as a "not secure" warning, can also prevent the form from working correctly. For more information on how to fix a "not secure" warning, see Why Your Website Says "Not Secure" (and How to Fix It).
  • A website lead form may not be properly integrated with the website's content management system (CMS).

Step-by-step fix: Troubleshooting a non-working website lead form

Check form settings

Check your website's lead form settings to ensure they are correct. Verify that the form is enabled and properly configured. Make sure the form's submission method is set to the correct option, such as email or database storage.

Verify plugin compatibility

Check if the lead form plugin you're using is compatible with your website's platform and other plugins. Outdated or conflicting plugins can cause issues with the form. Update or remove any incompatible plugins.

Server errors

Check your website's error logs for server errors related to the lead form. Look for errors like "500 Internal Server Error" or "POST request failed." This can help you identify the root cause of the issue.

  • Check your website's form submission settings to ensure they are correctly configured.
  • Test the form with a different submission method, such as a different email address or a temporary test email.
  • Clear browser cache and try submitting the form again.

Form plugin issues

If you're using a third-party plugin to manage your lead form, try deactivating and then reactivating the plugin. This can resolve any plugin-related issues.

Preventing website lead form issues

Regularly testing your website lead form can help you catch issues before they affect your business. Check your form on different browsers and devices, such as desktop and mobile, to ensure it works as expected. You can also use tools like Google's PageSpeed Insights to see if any technical issues are affecting your form's performance.

Keep your plugins up to date

Outdated plugins can cause website lead form issues. Make sure to update your plugins regularly to ensure you have the latest security patches and features. A single outdated plugin can compromise your entire website's security and performance.

Server maintenance is crucial

Your website's server plays a crucial role in processing form submissions. Regular server maintenance, such as backups and updates, can help prevent technical issues that might affect your lead form. Check your website's server logs to see if there are any errors or issues that need to be addressed.

  • Regularly test your website lead form on different browsers and devices
  • Keep your plugins up to date, especially those related to form functionality
  • Regularly update your website's server and perform maintenance tasks to prevent technical issues
  • Monitor your website's server logs for errors or issues that need to be addressed
