Hi, I tried adding a Group field using the Box Builder. I get errors right away when saving the Meta Boxes after adding that Group field. At the top of the admin page, I get...
Warning: call_user_func() expects parameter 1 to be a valid callback, class 'RWMB_Group_Field' not found in /wp-content/plugins/meta-box/inc/meta-box.php on line 353
and
Warning: call_user_func() expects parameter 1 to be a valid callback, class 'RWMB__Field' not found in /wp-content/plugins/meta-box/inc/meta-box.php on line 65
Since I was just testing this, I went ahead and then drug an existing text meta box field so that it appeared nested inside the Group field. After doing that, I got this additional error at the top of the page for the post type using these Meta Boxes...
Warning: call_user_func() expects parameter 1 to be a valid callback, class 'RWMB__Field' not found in /wp-content/plugins/meta-box/inc/meta-box.php on line 119
And on that post type edit page, in the middle of the Meta Boxes where the Group field "should" be, I get this error string...
Warning: call_user_func() expects parameter 1 to be a valid callback, class 'RWMB__Field' not found in /wp-content/plugins/meta-box/inc/meta-box.php on line 221
I guess all this means I can't use the Groups with the Box Builder, but I'm contacting you just in case I can and I'm just doing something wrong.
