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 1219
If I remove the group the data saves successfully.
Please help.
