    Error: Form ID did not match

    Asked by ashdav on September 06, 2012 at 08:57 PM


    I've got a client receiving the error 'Form ID did not match'.
    This is for the form located here.

    I'm not able to replicate the issue on my computer, so I'm really confused. Is there anything wrong with my form?

    Hi Ash,

    It looks fine to me.

    Have just done a test submission and all looks well.

    Is there is any chance of asking the person who had the problem to try again?

    It may have been an odd and very transient network issue.

    Thanks for your quick response!

    I'll ask the client to try again, and I'll keep testing the form on a few different browsers just to make sure all is good.

    Thanks for your help,

    I just made a test and just like you and fxr, I was not able to replicate the problem and saw your thank you page.

    I have removed my submission and your submissions counts was not affected by my test.

    We'll wait for your updates on this matter.

    Hi Guys,

    Clearing the browser's cache and cookies seems to have resolved the problem.

    Thanks for your help once again!
