Captcha image contains a backlink to our website. Please see example on the right.

My form submits only first time, and then it keeps showing same Captcha numbers and letters. What is the problem?
Please make sure your browser doesn't store the captcha image in the cache. Add this code inside <head> ... </head> tag:
<meta http-equiv="cache-control" content="no-cache" />
<meta http-equiv="pragma" content="no-cache" />

When I submit my form I always get this error: "Form protection code is incorrect", even if I know exactly it was correct. What is the problem?
Please verify your code. Value of the "skip_SnapHostID" field must match id of the captcha image.

Does it matter if my website is on UNIX or Windows platform?
You don't need to worry about your server OS - the script is located on our server.

I don't want to receive info from some of my form's field. What should I do?
Field names started with "skip_" will not be sent; use this for submit buttons, etc.
For example: name="skip_submit".

How do I get new "skip_SnapHostID"?
If you want a new "skip_SnapHostID" you need to refresh (click F5 or Ctrl+F5) this page. A new code will be automatically generated.

How many forms can I use on my website?
You can use as many forms on your website as you want.

Do you have any examples of forms which I can copy and use?
Yes, please see our Ready-To-Use Web Forms and our demo pages: Demo 1 and Demo 2.

How do I send form results to more than one email address?
To prevent an abuse of our BasicCaptcha script we do not support multiple email recipients. Our ProCaptcha script is a pay service allowing up to 48 email recipients.

Is there a way to hide the "send to" email address so bots don't pick that up?
With the BasicCaptcha script we cannot hide your email address because it has to be specified in your HTML code; so spam bots can pick it up. With ProCaptcha, your email address is stored in our database - it is not exposed to spam bots.

How do I remove lable from Captcha image?
There is a label shown on the BasicCaptcha image with a backlink to our website to advertize our services. You need to be a ProCaptcha customer to remove the label. See screenshot:

My forms are in French as well as English. Can your server take "multilingual" forms?
Yes. Please do not forget to place this META inside <head> ... </head> tag:

Do I have to use POST method in my form?
No, the script will work with both POST and GET methods.
