Please include a link to your Contact Form 7 form plus all your input in the of the CF7 interface. If others here are able to understand your actual problem, they may be able to offer a possible solution.

I did everything follow your turtorial
Then i insert [recaptcha] to default contact form, there is no custom.
When press “Submit”, it show “Failed to send your message. Please try later or contact the administrator by another method.”
I have disable your captcha and installed wp-recaptcha-integration and it works fine.

We’re also experiencing this problem on one of our websites.

We have it working fine on another website on the same server.

It says “
Validation errors occurred. Please confirm the fields and submit it again.”

Same problem. I did with tutorial

“Failed to send your message. Please try later or contact the administrator by another method.”

Digging further it has the error “Your entered code is incorrect” but my keys are correct. I’ve even deleted and recreated them and it still say incorrect.

Only on this one website (at the moment) but it was working with I initially set it up.

Any help?
