    Contact form will not submit

    Asked by guest_30113026096038 on January 12, 2013 at 10:05 AM

    I have made a simple contact form. Looks good and works well from your website.

    When I submit the code in my website the form appears, you can fill it in, but when I want to submit it the warning

    "Form ID did not match" so the message is not send.


    Question: what do I wrong?

    URL is not yet available. I am developing a concept website, using iWeb. Testing the site on my Mac causes the warning: Form id did not match

    Hi, when I run the contact form on your website it works excellent, same result as you. Problem is when I try to test it on my concept iWebsite on my Mac the error message 'Form id will not match' appears.

    After uploading my website I will test it from the internet.

    Thx for your help.
