Hi there, just looking to tidy u an issue.
In inc/functions.php line 114 you have:
$alt = graphene_get_attachment_image_alt( $attachment_metadata['attachment_parent'] );
On one of my sites this is throwing an error, as there is no attachment parent.
A quick fix for this would be:
if ( array_key_exists( 'attachment_parent', $attachment_metadata ) ) {
$alt = graphene_get_attachment_image_alt( $attachment_metadata['attachment_parent'] );
}
Not sure of the implications though.
