    Hello, I recently started to have issues with my registration page: Error! Nonce Security Check Failed! Go back to the registration page and submit again.

    I have seacrh for older threads and found that the fix should be by excluding this webpages from my cache plugin.
    I’m using Wp rocket and i have excluded this pages from caching.
    Still having this issue.

    Any suggestions?
    TIA

    The page I need help with: [log in to see the link]

    Does your server also implement a caching system by any chance? Do you use a CDN service? Do you have a security plugin that might interfere with our plugin?

    Kind regards.

    Thanks for the quick reply.
    I am using the new CDN service by Siteground. And actually, when you mention it ,it only started to happen when this was changed from Cloudflare CDN to Siteground CDN.

    Can you think of a fix? I will ask them to exclude this page from their caching system.

    The issue does not appear to be caused by the CDN as the issue persists even when accessing the website directly.
    The same is observed when putting the CDN in “Development Mode”.

    @omerdror, A nonce is a security token that WordPress can create for a given user in a given context. Our plugin uses it to protect the form from misuse. If the nonce is not present or doesn’t match when the form data is submitted, the validation will fail and this error is shown. Changing permalinks, applying automatic redirection, caching can cause this issue.

    Please disable all caching on that page and see what happens.

    I have Excluded this page from my Cache Plugin (WP rocket), but cant exclude it from the CDN of Siteground as they say: “As it is not possible to exclude individual pages from the CDN, you can consider disabling the CDN altogether. That is of course your developer is certain the issue is a result of the use of the CDN.”

    I rather keep using their CDN, and i’m sure i’m not the only Siteground client using your plugin.

    Do you have other suggestions?

    This is probably what is causing your issue unfortunately. Nonce is a token of security by WordPress needed as mentioned above by @affmngr.

    Kind regards.
