I have a problem when saving already published article (photo gallery). During creating or editing it I see this error:
Notice: Undefined index: display_field in file_field_widget_value function () (line 595 in the file /.../modules/file/file.field.inc).
and gallery will automatically change to unpublished, any editing is not possible. I found out that the "un-publishing" happends with all galleries, where are more than 163 photos . When I open the editing of gallery I can see only the first 163 pictures, the rest on the ftp.
To upload photos I am using a combination of sources filefield + filefield sources plupload. In the file file.field.inc line 595 is this:
$input[‚display‘] = $field[‚settings‘][‚display_field‘] ? 0 : 1;
Do you know where could be the problem? Can it be blocked by some module?
