Configuration Saved in back office, but nothing changed

Hello guys.

While I save a configuration’s change on the admin backoffice, it says it’s saved, but nothing changed. (on each page).

(It’s like it’s not saved).

But When I read the SQL core_config the data is correctly saved.

I did, of course, several cache clean.

Any idea about it ?

Ok… Tried for several minuted then, guess what…
Refresh clean do not work.
Flush cache config works…

Magento 2 is quite funny, I guess.
