Fixing Contact Form Issues: Troubleshooting Problems with WordPress Form Plugins

Contact forms are an essential component of any website, particularly for businesses looking to engage with their visitors or collect inquiries. WordPress, being one of the most popular content management systems (CMS), offers various plugins that allow users to add contact forms to their websites without requiring deep coding knowledge.

However, as with any digital tool, contact form plugins in WordPress are not without their issues. If you’ve landed on this blog, it’s likely that you’re facing some difficulties with your form—perhaps it’s not sending emails, or it’s not displaying correctly. These problems can be frustrating, but the good news is that they are usually solvable. This guide will take you through the common issues you might encounter with WordPress contact form plugins and how to troubleshoot them step by step.

Common Issues with WordPress Contact Forms

1. Emails Not Sending

One of the most frequent issues users face is that their contact form seems to work fine, but emails are not being delivered. This can be especially troublesome because, on the surface, everything appears functional. Visitors fill out the form, but you receive no notification in your inbox.

Why This Happens:

  • Server email settings: Your hosting server might not be properly configured to send emails. Some shared hosting providers disable PHP mail() function by default to prevent spam.
  • Spam filters: Sometimes, emails are sent successfully but end up in the spam folder due to the content of the message or how the email is structured.
  • SMTP Configuration: Simple Mail Transfer Protocol (SMTP) might not be correctly set up on your WordPress website, which is responsible for delivering emails.

Solution:

  • Install an SMTP Plugin: One of the best solutions for this issue is to install an SMTP (Simple Mail Transfer Protocol) plugin. SMTP is much more reliable than the default PHP mail function that WordPress uses. Plugins like WP Mail SMTP or Post SMTP allow you to connect your WordPress site to an SMTP service, which ensures better email deliverability.
  • Check Email Settings in Your Hosting Account: If you are not receiving emails, check with your hosting provider. They can help you determine if there’s an issue with the mail server configuration.
  • Whitelist Your Domain: Make sure that your email service provider has whitelisted the domain from which the contact form sends emails. This prevents the emails from being marked as spam.

2. Form Not Submitting or Giving Errors

Another common issue is that the form doesn’t submit. This could manifest as the page not refreshing or as an error message appearing when users try to submit the form.

Why This Happens:

  • Plugin Conflicts: WordPress is known for its vast library of plugins, but sometimes plugins can conflict with one another, causing forms to malfunction.
  • JavaScript Errors: Many WordPress forms use JavaScript for validation and submission. If there is a conflict or error in your website’s JavaScript, this can prevent the form from submitting.
  • Outdated Plugins: Running an outdated version of your form plugin or WordPress itself can also cause issues.

Solution:

  • Deactivate Other Plugins: Start by deactivating all other plugins except the contact form plugin to check if there’s a conflict. If the form starts working again, reactivate the plugins one by one to find the culprit.
  • Check Browser Console for Errors: Use the browser’s developer tools (right-click > inspect > console) to see if there are any JavaScript errors when trying to submit the form. These errors can help identify what’s causing the problem.
  • Update Plugins and WordPress: Always ensure that both your WordPress core and the contact form plugin are up to date. Developers frequently release updates to fix bugs, patch security vulnerabilities, and improve compatibility.

3. Captcha Issues

Many websites use CAPTCHA to prevent spam submissions. CAPTCHA is a tool that asks users to verify that they’re human by entering a code, ticking a box, or completing a challenge. However, sometimes CAPTCHA can fail or block legitimate users from submitting the form.

Why This Happens:

  • Invalid API Keys: Some CAPTCHA services, such as Google reCAPTCHA, require API keys to function. If these keys are missing or invalid, CAPTCHA will fail.
  • Conflicting JavaScript: Like the form submission issues, CAPTCHA relies on JavaScript to work. If there’s a conflict, CAPTCHA won’t display or will prevent the form from submitting.
  • Caching Issues: If you’re using a caching plugin, it can sometimes interfere with CAPTCHA scripts, leading to it not working correctly.

Solution:

  • Check API Keys: Ensure that your CAPTCHA is correctly set up with the appropriate API keys. If you’re using Google reCAPTCHA, you’ll need to create API keys from the Google reCAPTCHA website and add them to your plugin.
  • Use Alternative CAPTCHA Solutions: If Google reCAPTCHA is causing too many issues, consider switching to an alternative CAPTCHA solution like hCaptcha or WP Armour. These are often simpler to implement and less likely to encounter issues.
  • Disable CAPTCHA for Debugging: Temporarily disable CAPTCHA to see if the form works without it. If it does, then CAPTCHA is the issue, and you can troubleshoot from there.

4. Contact Form Styles Not Displaying Correctly

Sometimes the contact form is working, but it doesn’t look right. The fields may not align properly, or the form might not match the rest of your website’s design.

Why This Happens:

  • Theme Conflicts: Your WordPress theme might have CSS that’s overriding the contact form plugin’s styles.
  • Responsive Design Issues: The form may look fine on a desktop but break on mobile devices.
  • Custom CSS: If you’ve added custom CSS to your site, it might be conflicting with the form’s default styles.

Solution:

  • Inspect with Developer Tools: Use your browser’s developer tools (right-click > inspect) to examine the form’s HTML and CSS. This will help you identify if any of your theme’s CSS is overriding the form’s styling.
  • Add Custom CSS: If the form isn’t displaying as expected, you can add custom CSS to fix the styling issues. Many form plugins allow you to input custom CSS directly within the plugin’s settings.
  • Check Responsiveness: Ensure your form is responsive by testing it on different screen sizes and adjusting the CSS as needed. If your form plugin doesn’t support responsive design, consider switching to a plugin that does.

5. Form Fields Not Displaying

You might encounter situations where certain form fields aren’t displaying or are missing altogether. This could prevent users from submitting crucial information, leading to incomplete submissions.

Why This Happens:

  • JavaScript or CSS Conflicts: Again, conflicts with your theme or other plugins could be causing form fields not to display.
  • Field Visibility Settings: Some contact form plugins allow you to set conditions on when fields appear (e.g., based on user input). If these conditions are incorrectly configured, certain fields may not show up.
  • Form Cache: If your website is heavily cached, it could be serving an outdated version of the form without the recent changes you made to it.

Solution:

  • Clear Cache: If you’re using a caching plugin, clear the cache to ensure that your users see the latest version of the form.
  • Check Visibility Settings: Review the form’s field visibility settings to ensure no fields are accidentally set to be hidden.
  • Deactivate Other Plugins: As with other issues, try deactivating other plugins to rule out any conflicts.

6. Spam Submissions

Even with CAPTCHA in place, spam submissions can still slip through, especially as bots become more sophisticated. Not only can spam fill your inbox with junk, but it can also clog up your database with unnecessary entries.

Why This Happens:

  • Weak CAPTCHA Implementation: Some CAPTCHA systems are easy for bots to bypass.
  • No Additional Spam Protection: Many WordPress contact forms rely solely on CAPTCHA, without additional layers of security.

Solution:

  • Use a Stronger CAPTCHA: Google reCAPTCHA v3 is designed to offer more sophisticated bot protection without requiring user interaction. You can also use honeypot techniques, which are invisible fields designed to catch bots.
  • Add Akismet: Akismet is an anti-spam plugin that works well alongside contact forms. It helps filter out spam submissions by using algorithms that detect patterns in bot submissions.
  • Limit Submissions: Some form plugins allow you to limit the number of submissions from the same IP address. This can help reduce spam by preventing multiple submissions from the same bot.

7. Form Duplicating Submissions

In some cases, users may submit the form once, but you receive multiple identical submissions. This can happen due to user error or technical glitches.

Why This Happens:

  • Slow Form Loading: If the form takes a long time to submit, users may click the submit button multiple times, thinking it hasn’t gone through.
  • Caching: Caching can cause users to submit duplicate forms if the cache isn’t properly configured to handle form submissions.

Solution:

  • Disable Button After Click: Many form plugins offer an option to disable the submit button after it’s been clicked once. This prevents users from submitting the form multiple times.
  • Check Caching Settings: Ensure that your caching plugin or server cache is properly configured to exclude form submissions. This prevents cached versions of the form from causing duplicate submissions.
