You need to ensure the webserver user has write permissions. Depending on the setup this often requires 775 or even 777 permissions on the folder.
Just because the directory is writable to you (when you log in), does not mean that it is writable to PHP / Apache / whatever web server you have. Depending on your server configuration, PHP likely runs with an entirely different set of permission. You can either lookup the permissions for your web server or set the directory to 777 and then backoff from there to determine the correct permissions for the directory.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
