Hi @Nasseer,
Next time, it’s best to start a new topic (or find an existing relevant one) – those questions aren’t related to this topic. But I think the problem is probably still to do with file permissions in your files_dir. It’s not enough to work with just the numeric permissions (e.g. 755), you’ll also need to work with the file ownership. See How should file permissions be set? for details.
