Configuration Saved, but nothing change

[nervusdm]

I do have a strange problem on my Magento 2.X install.

While I save a configuration's change on the admin backoffice, it says it's saved, but nothing changed.

(It's like it's not saved).

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

But on backoffice it's not.

I did, of course, several cache clean.

Hi @nervusdm,

This issue may be from cache.
Flush the cache once.

php bin/magento cache:flush

If still nit work then manually delete once var/cache folder and make sure that var/ folder have write (777) permission.

I hope it will help you!
