I am using the builder to create a custom meta box with a group. I get the following error when trying to save:
Warning: array_map(): Argument #2 should be an array in [my-site-info]/wp-includes/post.php on line 2072 Warning: Cannot modify header information - headers already sent by (output started at [my-site-info]/wp-includes/post.php:2072) in [my-site-info]/wp-includes/pluggable.php on line 1219If I remove the group the data saves successfully.
Please help.

Hi Purdue,
I guess the problem comes from the group settings. Please share the code of the meta box for debugging.
I am using all the default settings. By simply placing an empty group in the Fields area I get the error.
add_filter( 'rwmb_meta_boxes', 'your_prefix_register_meta_boxes' ); function your_prefix_register_meta_boxes( $meta_boxes ) { $meta_boxes[] = array ( 'title' => 'Test Box', 'id' => 'test-box', 'post_types' => array( 'page', ), 'context' => 'normal', 'priority' => 'high', 'fields' => array( ), ); return $meta_boxes; }(Looking closer at the code above I see that an empty group is not even output into the Code tab.)
Even with a more realistic example (a group with a field inside it), I still get the error.
add_filter( 'rwmb_meta_boxes', 'your_prefix_register_meta_boxes' ); function your_prefix_register_meta_boxes( $meta_boxes ) { $meta_boxes[] = array ( 'title' => 'Test Box', 'id' => 'test-box', 'post_types' => array( 'page', ), 'context' => 'normal', 'priority' => 'high', 'fields' => array( array ( 'id' => 'group_2', 'type' => 'group', 'name' => 'Group', 'fields' => array ( 0 => array ( 'id' => 'text_2', 'type' => 'text', 'name' => 'Text Field', ), ), 'default_state' => 'expanded', ), ), ); return $meta_boxes; }Hi Purdue,
Thanks a lot for bug reporting. I can replicate the bug in the Meta Box Builder (it’s a bug in the Builder, not in the Group extension). I’ll fix and release a new version soon.
Great. I look forward to the update.
Hi, I’ve just updated the plugin. Please check it.
Thanks
That seems to have worked. I will let you know if I experience any issues using it in production, but thank you for your quick reply and fix!
