Invalid form nonce

  • Hello,
    On one of the websites we use AF on, upon submission instead of getting redirected to the thank you page I get the following error

    Invalid form nonce

    The form is registered programmatically. The error only occurs following upgrade from 1.6.7 to 1.6.9
    Would appreciate any ideas on how to resolve this.

    Hi!

    The nonce was introduced in 1.6.9 but definitely shouldn’t fail in a situation like this. There is a chance that caching plugins could cause an issue like the one you are seeing. Are you using a caching solution?

    I also had reports of that from a site using W3 Total Cache

    Caching could definitely cause issues in general. The form page can’t be served from cache as it will then include an outdated nonce, causing the error we’re discussing. I would recommend adding an exclusion rule to your caching plugin for your forms.
