This is one of the most common and frustrating Contact Form 7 errors:
“There was an error trying to send your message. Please try again later.”
This message usually means the form submission reached the server, but something blocked the email or processing.
Let’s fix it step by step.
🚨 Why This Error Appears
This error is usually caused by:
-
Email sending failure
-
SMTP not configured
-
Server mail restrictions
-
reCAPTCHA blocking the submission
-
Security or firewall rules
-
REST API or AJAX blocked
-
Hosting misconfiguration
🔧 FIX 1 — Check Contact Form 7 Error Logs
Go to:
WordPress Dashboard → Contact → Contact Forms → Status
Check for:
-
REST API errors
-
Mail sending errors
-
reCAPTCHA errors
-
Configuration warnings
Fix anything marked in red.
🔧 FIX 2 — Configure SMTP (Most Important Fix)
PHP mail() fails on most hosts in 2026.
Install an SMTP plugin and configure:
-
Gmail SMTP
-
Outlook / Office365
-
SendGrid
-
Mailgun
-
Amazon SES
SMTP ensures authenticated and reliable delivery.
🔧 FIX 3 — Fix the “From” Email Address
Incorrect From email causes silent failures.
❌ Wrong:
✅ Correct:
Always use a domain-based email.
🔧 FIX 4 — Check SPF, DKIM & DMARC
Missing DNS records cause rejection.
Ensure:
-
SPF includes your mail provider
-
DKIM enabled
-
DMARC added
Without these, emails may fail without warning.
🔧 FIX 5 — Disable reCAPTCHA Temporarily
reCAPTCHA can block submissions silently.
Test by:
-
Temporarily disabling reCAPTCHA
-
Submitting the form
-
If it works, reconfigure reCAPTCHA v3 keys
Make sure keys are valid and linked to a Cloud project.
🔧 FIX 6 — Disable Security & Firewall Plugins
Security plugins may block CF7 requests.
Temporarily disable:
-
Wordfence
-
iThemes Security
-
All-in-One Security
-
Cloudflare WAF
If fixed, whitelist:
-
admin-ajax.php
-
REST API
-
CF7 scripts
🔧 FIX 7 — Check REST API & admin-ajax.php Access
Contact Form 7 requires:
-
REST API enabled
-
admin-ajax.php accessible
Hosting firewalls or security rules may block these endpoints.
🔧 FIX 8 — Check Hosting Error Logs
Check your hosting panel for:
-
PHP errors
-
Mail errors
-
Permission issues
-
Memory limits
Look for HTTP 403, 500, or mail-related errors.
🔧 FIX 9 — Update PHP Version
Contact Form 7 works best with:
-
PHP 8.0 or 8.1
Outdated PHP versions may cause failures.
⭐ Final Thoughts
This error usually means email delivery or server communication failed.
Once you:
✔ Set up SMTP
✔ Fix DNS records
✔ Whitelist CF7 in security plugins
…the error disappears and forms send correctly.
