Hello there!

I have a plugin that uses the following structure:

piklist( 'field', array(
    'type' => 'group',
    'label' => '3-In-1 Settings:',
    'description' => 'desc',
    'add_more' => true
    ,'fields' => array(
		array(
	    	'type' => 'select'
			,'field' => 'a31_post_id'
			,'value' => '-1'
		    ,'columns' => 6
			,'label' => 'Artikel'
			,'description' => ''
			,'choices' => array('-1' => 'Wähle eine Seite') + piklist(
	              get_posts(
	                 array(
	                  'post_type' => array('page', 'post', 'stock', 'person')
	                  ,'posts_per_page' => -1
	                 )
	                 ,'objects'
	               )
	               ,array(
	                 'ID'
	                 ,'post_title'
	               )
	            )
		)
	)
	,'validate' => array(
	  array(
	    'type' => 'limit',
	    'options' => array(
	      'min' => 0,
	      'max' => 3
	    )
	  )
	)
  ));

This has worked very well and still does on my development server, but on the production system itself, none of the changes are saved.

I had this problems on more sites, but it was enough to add

add_action( 'init', 'piklist_remove_post_type_support', 10 );
function piklist_remove_post_type_support() {
  remove_post_type_support( 'page', 'custom-fields' );
  remove_post_type_support( 'post', 'custom-fields' );
}

to get it working again. I have already done that on both systems but still, nothing gets saved.

I somehow believe, that the transformation (there’s once this transformation step) has not taken place on the production server – could that be and if yes, can it be somehow triggered?

The database on both systems is 1:1 the same. As well as the filesystem (i use git to sync both, besides files that are in git.ignore.

I currently run out of ideas how to solve this.

best regards, Harald
