Thank you for your reply. I created the wpcf7_captcha folder and assigned rights to it.
Pasting this short code
[captchac your-captcha]
<label>Enter the code: [captchar your-captcha]</label>
into the HTML tab directly under the Contact Form 7 short code in the editor results in me getting the working form, but the above Really-Simple CAPTCHA short code is appearing directly below the Send button on the published page. There is no input form fields or any text whatsoever.
I honestly don’t know why its not working.
