mfile upload error

multiple file upload(mfile) upload error.
when I upload someting using file type “mfile”.
code can’t detact to file, but an array.
so back-end view and email will show as a string that has no hyper link.
I read the code, I think it goes to an array for conditional expressions and there’s no hook or filter I can do.
could you please add a filter or fix the conditional expressions
