    Have you modified the code at all? The only reason you’d be getting this is if the hidden nonce value isn’t available.

    To remove the security field, you’ll need to purchase the Pro version.

    No code was modified , maybe it’s a problem with the plugin super cache or the navigator Internet Explorer.

    Anyway, seriously guys you have the best plugin and low cost price for noobs final users who want to create forms with visual UI. but a bug like this one can create for webmasters big problems with their customers when they say to them that they have to buy the plugin for making it work again lol.
    If there is a free version for this plugin the “spam buggy verification” have to be optional.

    Yeah, if you are using a caching plugin you will need to make sure the page with your form is not cached.

    I’m having this same problem. I don’t think it has always done this, but just this weekend I’ve been getting complaints that they can’t send the form and get the “Nonce Value” error.

    I tried it myself and didn’t get the error (in Firefox) then I tried it in IE, and I got the same error. I cleared the cache for the page and still get the error.

    I have not changed anything in the Visual Form Builder recently. If I do upgrade to the pro version, what do I need to do to make sure the form works in Internet Explorer?

    I had this error and I am hardly likely to buy the pro version if you can’t even sort out the bugs in the free version.

    I would have been interested in the pro version or at least to see what it can do, but losing enquiries so will just install Contact7 and be done with

    So how much time would it have taken for the plugin author to investigate this as I did today.

    The solution is to exclude the the URL in WP Super Cache.

    Click on the Advanced Tab, scroll down to box under the text below this:

    “Add here strings (not a filename) that forces a page not to be cached. For example, if your URLs include year and you dont want to cache last year posts, it’s enough to specify the year, i.e. ’/2004/’. WP-Cache will search if that string is part of the URI and if so, it will not cache that page.”

    Enter part of the URL that has the form

    Click Save

    Problem solved!

    The nonce feature was removed a long time ago so you are complaining about something that is no longer a problem.
