Title: After Upgrading PublicPress Permissions (Version 4.7.0) getting ACF nonce issue Last modified: March 26, 2026 --- # After Upgrading PublicPress Permissions (Version 4.7.0) getting ACF nonce issue * Resolved [aaresrikanth](https://wordpress.org/support/users/aaresrikanth/) * (@aaresrikanth) * [2 weeks, 2 days ago](https://wordpress.org/support/topic/after-upgrading-publicpress-permissions-version-4-7-0-getting-acf-nonce-issue/) * Hi, * I am encountering an issue with the Advanced Custom Fields (ACF) plugin after upgrading to the latest version of the **PublicPress Permissions** plugin (Version 4.7.0). Previously, everything was functioning correctly, but after the upgrade, I started receiving the following error when updating a custom post type post: * **“Validation failed. ACF was unable to perform validation because no nonce was received by the server.”** * This issue occurs when trying to save or update posts that include custom fields created by ACF. It seems that the recent update of the **PublicPress Permissions plugin (Version 4.7.0)** has caused this conflict with the nonce validation in ACF. * ACF Plugin Version : 6.7.1 * WordPress Version : 6.9.1 * I suspect the conflict is related to the PublicPress Permissions plugin update, which is affecting the nonce validation process in ACF. * Could you please assist in investigating and resolving this issue? Any help or guidance on how to fix this would be greatly appreciated. * Thank you for your time and support. I look forward to your prompt response. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fafter-upgrading-publicpress-permissions-version-4-7-0-getting-acf-nonce-issue%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Support [Riza Prihananto](https://wordpress.org/support/users/rizaprihananto/) * (@rizaprihananto) * [2 weeks, 2 days ago](https://wordpress.org/support/topic/after-upgrading-publicpress-permissions-version-4-7-0-getting-acf-nonce-issue/#post-18863577) * Hi [@aaresrikanth](https://wordpress.org/support/users/aaresrikanth/) , Thank you for using the PublishPress plugin.

After making this change, the functionality is working as expected. * Thank you once again for your assistance.
