    Has anyone else had this error when someone submits their email into a form?
    “Error: Couldn’t verify form submission”

    Did you manage to resolve your issue? How?

    It seems to be fixed temporarily if I clear the cache in WP Rocket every day but still this error should not happen.

    I run WP Rocket and Cloudflare if that helps as it may be a caching issue although not sure why.

    It seems some others have had this issue of the error message in the past. How did you fix it or were you not able to?

  • Hey. I have the exact same problem. I need help… This really causes problems

    BTW Cache deleting works. I have Autoptimize and WP Fastest Cache enabled. I guess one of those Plugins causes the errors… But i need those plugins. Any fixes?

    I have the same issue, but it is strange as i can get it to work sometimes. Basically, if you open up the form in the admin for the Optin Forms, and just click ‘Save’ it appears to work o.k and the submission is processed.. however after a while it reverts back to having a problem. Also i had someone else check the form from a different location and computer and they could not get it to work, even after the resave.

    Really need a fix for this ASAP please, otherwise i will have to get rid of the plugin.

    the problem could be related to the fact that the HTML contains something called a nonce (a security token that is valid for a limited amount of time) which is checked upon form submission. if that nonce is being cached by the page cache (wp rocket/ wp fastest cache) for longer then the token validity, then the nonce check fails after said expirey time and the form submission does not work. If that is the case you would need to alter page caching settings to set it so HTML (pages) can only remain in cache for the same amount of time the nonce is valid.

    Hello there,

    We agree with Frank on this. The issue is most likely the nonce being cached by the cache plugin.

    We recommend adjusting the cache settings so that the nonce remains valid for successful form submission.

    Thanks.

    Hi, I am dealing with the same issue , in my case I use Autoptimize and w3tc.
    @fatcatapps what are your recomandation for cache settings so that the nonce remain valid?
