Turning on "custom css for all ALB" support crashed my local WP/"framework"

Hello, i tried to turn on the custom css support for all ALB elements and since then when i try to save/actualize a page in the backend, the page always will show a blank page afterwards (by the way, it saved itself but just leave a blank page, reloading doesn’t help).
I also deleted the css ALB code again from the function.php (enfold and child), restarted the server and the computer, but nothing has helped.
I guess i hasn’t forgotten any code … or added:
