用xampp解决问题

Question

I am developing my WordPress website locally using XAMPP server, but Contact Form 7 Captcha functionality does not work. That is, clicking on the Submit button, a spinning arrow appears and the form does not do any thing.

<p>Nom (required)<br />
    [text* your-name] </p>

<p>Email (required)<br />
    [email* your-email] </p>

<p>Telephone (required)<br />
   [text phonenumber]</p>

<p>Sujet<br />
    [text your-subject] </p>

<p>Message<br />
    [textarea your-message] </p>

<p>Remplir le code : [captchac captcha-914 bg:#01DF01 size:m]<br />
[captchar captcha-914]
     </p>

<p>[submit "Send"]</p>
