Can't use ACF with EA-Starter

[Boa2]

When I switch from the theme TwentyTwenty to EA-Starter-Master I loose the menu "Custom Fields" from my ACF Pro - so I can not use ACF with the new build of EA-Starter (downloaded today: 2019-11-29.).
I could use ACF with an EA-Starter build that I downloaded on 2019-09-06.
Help appreciated,
Andrea

You need to add define( 'WP_LOCAL_DEV', true ); to wp-config.php, or comment out this line.

This feature allows you to use ACF to create metaboxes in your development environment, but prevents anyone from editing or deleting them in the production environment.

Adding define( 'WP_LOCAL_DEV', true ); did not work for me. I had to comment out the line you marked in acf.php.
Thank you!
