Issues after update

We found the issue, our Caching plugin. We tried an other one, same issue.

So your update somehow broke all caching plugins. Back to wpdiscuz previous version i guess.

We’ll check and get back to you ASAP.?

I have the same error, but I don’t have any cache plugin. This afternoon I will look into it…

@eltiorufi Ok, maybe you have some other type of caching, CDN for example?

No CDN no caching. I’m still testing, but I think is conflict with Polylang plugin.

In a while, can confirm.

EDIT: Not Polylang. Still testing…

I deactivated all plugins, even change the theme to “Twenty Twenty-Three” and I still have the same error:

[10-Aug-2023 11:26:07 UTC] PHP Warning: Cannot modify header information - headers already sent in /home/mysite/public_html/wp-content/plugins/wpdiscuz/utils/class.WpdiscuzHelper.php on line 162

WordPress: 6.3
PHP 8.0.30

I have my site on my own server with cPanel if you need more information

@eltiorufi This IS a caching issue. The line with the error is

setcookie(self::GLOBAL_NONCE_NAME .'_'. COOKIEHASH, $nonce, time() + 60 * 60 * 10, '/', "", false, true);

and nonce is usually related to caching.

WordPress Nonce Cache

WordPress Nonces system protects URLs and forms from certain types of misuse, malicious or otherwise.

The meaning of the Nonce is “number used once” and a Nonce has a life time. If it expired, the request which contains a Nonce cannot be completed and the request fails.

If a page is cached, the Nonce value is cached as well. If the cache is not cleared “twice a day”, the Nonce is expired so we need to add a cache timeout rule as below.

Same error filling up my error log after the latest update. Caching is currently disable on the site.
