Same for me. I cannot even show a tab. What’s working fine for custom post types, doesn’t work with users. I tried to copy code from piklist demos, but this doesn’t help.

@efegue: Your solution hint is very appreciated. Thanks for it. I found another thread from August 2015, where the solution is very similar. The only difference: It uses the unset-function, so that the field gets ignored by the Events Manager-Post Meta-Save-Function:

add_action('em_event_save_meta_pre', 'prevent_double_serialization_by_em_and_piklist');
function prevent_double_serialization_by_em_and_piklist($event) {
    unset( $event->event_attributes['field_name_of_the_piklist_add_more_field'] );
}

@sbruner: I think this topic can be marked as resolved with the exception of the post 5960 from nakanaa above.

Thanks for the hint, Steve. But it doesn’t work. I made a 2-minute-screencast, which shows, what’s happening: Youtube.

This topic can be closed, because I made a new one here.

Hi Steve

Has the bugs with file upload in group fields been resolved? Because I’m also having very strange things happening when using the following code. For the moment I will try with ungrouping the field.

Kind regards
Björn
