 * Followers of my blog recently got a lot of “nonce verification failed” messages
   when trying to leave a comment. It sometimes works, but most of the time it doesn’t.
   I cleared the cache, re-connected Jetpack and it still happens. All plugins and
   the theme are up to date.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcomment-error-nonce-verification-failed%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@miarr0wporg](https://wordpress.org/support/users/miarr0wporg/),
 * Thanks for reaching out. It looks like you have WP Fastest Cache installed, which
   has the ability to minify JavaScript. There is a [known issue with Jetpack](https://jetpack.com/support/getting-started-with-jetpack/known-issues/#plugins-minify)
   where plugins that minify JavaScript can break Jetpack features.
 * As a first step, please ensure that this feature is not active on your site.
 * If you’re still having issues after ensuring that feature is disabled, and you’ve
   cleared caches again, please [contact us](https://jetpack.com/contact-support/?rel=support&hpi=1)
   and mention this thread.

 * Hello [@miarr0wporg](https://wordpress.org/support/users/miarr0wporg/),
 * Do you have updates about that? We usually close inactive threads after one week
   of no movement, but we want to make sure we’re all set before marking it as solved.
   Thanks!
