Page or article not updating

[anonymized_14292070]

I have a bug since the 4.4 update.
I run WP on Nginx 1.9 with MariadDB and no cache plugin.

I can't update some articles and pages. When I update a page for example, I get the message "update successful" but nothing changed on the page. I can't do anything with it, even delete it !
But I can modify others articles without no problem so I don't know where the problem come from. Also, the MySQL user for the WP has every right on it.

Thanks for the support!

Hi @Angristan,

This sounds like some kind of a caching or a database issue specific to your configuration.

Unfortunately, there's not much we can do from the WordPress core side until there are clear steps to reproduce the issue on a clean install.

Please try the support forums if you need help with your site: ​https://wordpress.org/support/.

caused by pagespeed.

Edit : This bug is not caused by pagespeed nor Nginx, HHVM, PHP-FPM... This a database problem. I will search into the forum

In fact I am sure this is a WordPress bug, because I don't have any cache, and I can't even delete some pages or articles.
