The arrows spin but nothing happens.

Please describe your problem in more detail. Include all your input in both the Form section and Mail section of the CF7 interface and a link to your CF7 form if possible. If others here are able to understand your actual problem, they may be able and willing to offer a possible solution.

This is what i got:

<p>Tu nombre (requerido)
[text* your-name] </p>

<p>Tu Email (requerido)
[email* your-email] </p>

<p>Asunto
[text your-subject] </p>

<p>Tu Mensaje
[textarea textarea-429 /300]</p>

[captchac captcha-367]

[captchar captcha-367]

<p>[submit “Enviar”]</p>

If i remove both the [captchac captcha-367] and [captchar captcha-367] the script works fine (the arrows spins and then the message is sent) but when i add those two lines the arrows spins but nothing happens next, i dont know why.

This is most likely due to a Javascript conflict. Could be with the Captcha plugin you are using but could also be with your current WordPress theme or one of the other plugins you are using – see Solving CF7 Javascript Conflicts.

Remember that a problem in one script can cause issues in another. For example, some jQuery errors can stop jQuery processing any more script, which can make the culprit hard to find. A jQuery error in one of your plugins or your themes javascript files can stop jQuery processing before it gets to the CF7 script.
