Notice: Array to string conversion in oik-clone\admin\class-oik-clone-post-file.php

[bobbingwide]

When re-cloning an attachment the following notice is produced:

Notice: Array to string conversion in C:\apache\htdocs\wordpress\wp-content\plugins\oik-clone\admin\class-oik-clone-post-file.php on line xxx

This is due to the post_meta data already containing information about the target post and the time that the cloning was last performed.

e.g.

[0] => (string) "target"
[1] => Array
        [id] => (integer) 10583
        [cloned] => (integer) 1442924512
