When editing contact information using content type webform multiple instances of the following error occurs
-
Warning: array_filter() expects parameter 1 to be array, string given in field_collection_item_is_empty() (line 591 of /sites/all/modules/contrib/field_collection/field_collection.module).
Thanks
This error comes from Field Collection version 7.x-1.0 beta, you could take a look at https://www.drupal.org/node/2599248, there is an enclosed fix patch or you can fix by yourself:
Go to Modules/Contrib/Field_collection,Open File field_collection.module, Line 591
Replace
With
$all_boolean = $instances && !(bool) array_filter($instances, '_field_collection_field_is_not_boolean');
