Config working using app_dev.php but not using app.php

[matdev]

I have the following config in my app/config/config.yml file

stfalcon_tinymce:
    theme:
        simple:
            plugins: "link image"
            height : "480"

The tinymce editor is picking up this config fine when I use app_dev.php, but as soon as I use app.php, it's no longer working: I get the default simple theme config

hello @matdev it look like you forgot to clear the production cache with
php bin/console cache:clear --env=prod

That was it ! Thanks very much @nykopol
