File permissions

*
The php installer needs to be able write files during installation, which should be restricted again afterwards. It needs to create/have write-access to:
o
The main installation directory (for creating .htaccess file and assets directory)
o
The mysite folder (to create _config.php)
o
After the install, the assets directory is the only directory that needs write access.
+
Image thumbnails will not show in the CMS if permission is not given

When you perform the installation you will see certain files and folders that require full read-write-update permissions (chmod 777). For information as to how or what these are have a look at:
