I know that I'm supposed to change my permissions to 666 to make my files writable in order to change them on the dashboard. But I've also seen someone say they should be changed to 766. Is that correct? Which is preferable? Why would I choose one over the other?
Also, is it adviasable, from a security standpoint, to just let my files sit with a permission of 666 or 766? Or should I go back and change them to 644 when not working with them?
Thank you. I hope I've been clear.
