Nonce fail way too often

During last 24 hours I experienced Nonce fail 10-15 times. I understand the security mechanism and read previous topics such as:
https://eventespresso.com/topic/nonce-fail/
https://codex.wordpress.org/WordPress_Nonces

The thing is it happens too often and in non-security context. For example I wanted to set Payment pending for 2 tickets and I got nonce fail.

It also happens almost periodically during editing message templates. If I left template opened in one tab, went to another one to see or copy something and came back later (even 10 or more minutes) – after submitting changes there was nonce fail.

Either some timeout is too short or there is serious problem with using multiple tabs in browser.

I tried again the same operation as at the printscreen with long waiting before submitting and nonce did not happen. It seems to be multiple tabs issue.

Hi,

Unless there’s a plugin on your site that’s modifying the nonce lifetime, the open tabs should be OK for between 12 and 24 hours.

May I ask what’s the exact error message you’re seeing when there’s a nonce fail?

It is the linked printsreen. Just text “Nonce fail” and link to you youtube.

If it’s not caused by another plugin resetting the session, it may help to edit the wp-config.php file and replace the contents of the Authentication Unique Keys and Salts section.

You can get new keys and salts here:
https://api.wordpress.org/secret-key/1.1/salt/

After those are changed you’ll need to log back into your site.
