Newbie here and after installation I was having problems uploading, and following advice in the forum, reset some permissions, which does not help when the ownership of your uploads folder is incorrect. After my host fixed that, I reset all of my permissions back as suggested here in the forum. Once question I still have though, is what should the permission be for the public_html folder itself? I don't remember changing the setting on that one, but right now it's at 777. Should it be 755?
