Resolving Drupal Contact Form Errors: A Comprehensive Guide

If you're encountering errors with your Drupal contact form, fear not! This guide will walk you through a series of steps to identify and resolve the issue. Whether it's a simple configuration mistake or a more complex error, this guide has you covered.

1. Enable Error Reporting

The first step is to enable error reporting in your .htaccess file to get more detailed error messages. This can significantly help you identify the source of the problem. Here's how you do it:

Step 1. Modify .htaccess File

Edit your .htaccess file and set the error level to verbose:


config[system.logging][error_level]  verbose

2. Check Logs

If the error message isn't clear, check the Recent log messages in the Drupal admin interface. Additionally, you can look at the server logs like Apache or Nginx for more context:

Step 2. Access Drupal Admin Logs

Go to Reports Recent log messages to view any relevant error messages.

3. Clear Cache

Sometimes caching can cause unexpected errors. Clear the Drupal cache:

Step 3. Clear Drupal Cache via Interface

Navigate to Configuration Performance Clear all caches

Step 4. Clear Drupal Cache via Drush

Alternatively, use Drush, the command-line shell for managing Drupal:


drush cr

4. Check Form Configuration

Ensure that the contact form is correctly configured. Verify required fields are filled out and custom validations are working:

5. Review Custom Code and Modules

If you have custom modules or themes, check for code that may interfere with form submission. Temporarily disable custom modules to see if the error persists. Update any contributed modules that may have bugs or compatibility issues:

Step 5. Test Without Custom Modules

Temporarily disable custom modules and see if the error disappears:


drush pm-disable custom_module_name

6. Check Permissions

Make sure the user role submitting the form has the necessary permissions to access and submit the contact form:

7. Update Drupal Core and Modules

Ensure your Drupal core and all modules are up to date as bugs in older versions may have been resolved in newer releases:

To update Drupal core, go to Reports Status Report and follow the on-screen instructions.

8. Rebuild the Form

If the issue persists, consider rebuilding the contact form. This can be done by recreating the form in the admin interface or using Drush:

Step 8. Rebuild Form Using Drush


drush entity:delete form_display --bundlecontact_form

9. Consult Community and Documentation

As a last resort, consult the Drupal community forums or Drupal documentation for further assistance:

10. Backup and Restore

If none of the above steps resolve the issue, consider restoring from a backup if one is available:

Step 10. Backup and Restore with Drush


drush site-backup

By following these steps, you should be able to identify and resolve any unexpected errors in your Drupal contact form. Remember, maintaining a well-configured and up-to-date Drupal setup is key to avoiding these issues in the first place.
