I have no clue how to chmod666 someone please tell me.
Through your ftp client, mark the file/folder... click CTRL+O, type 666, then ok.
Using FlashFXP myself, and that's the way to do it.
In SmartFTP you connect to your server, mark the file/folder and press Alt-Enter.
You mmust select the requris files from the installation Using on FlashFxp right click on the mouse and "Chmod" change from 655 i think to 666 or 777 nvm.
