Check that file what is on line 59.
Also your osclass version matter

    if(isset($item["locale"]) && !empty($item['locale']) && isset($item["locale"][$locale]) && isset($item["locale"][$locale][$field])) {

Osclass v4.4.0

Just on first look, maybe this could work.
if(is_array($item) && isset($item["locale"]) && !empty($item['locale']) && isset($item["locale"][$locale]) && isset($item["locale"][$locale][$field])) {

I changed the new code and so on

@Stefanescu Marius
Dont mess different issues.

It's weird issue there, maybe try to replace complete content of condition with
if(@$item["locale"][$locale][$field] <> '') {

thanks it works perfectly
