// Error message appears on the edit-post.php page (not on the ACF plugin page)

Yes, it works. But if i remove the “if(is_string($string))”-construct it fails the same way as before.

First field is a repeater field:

Second field inside the first, too:

Relevant options of the second field (select, with multiple selection true):

My EAE calls in the function.php:
add_filter(‘acf/load_value’, ‘eae_encode_emails’);
add_filter( ‘walker_nav_menu_start_el’, ‘eae_encode_emails’ );

Thanks Till

Mh. Sorry guys. Miss configured wordpress installation by a Coworker. There was some preg_replace lines in the functions.php.
