xfrancis2 on "[Plugin: Contact Form 7] The arrows spin but nothing happens."

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.
