Managing Resources

Hi,

I'm trying to use a different folder to upload my assets, however something is not quite right. i'm using the below code example below in the config.php file

define('PERCH_RESFILEPATH', '/var/www/mysite/public_html/files');
define('PERCH_RESPATH', '/files');

The folder I have made is writable, however if I'm not sure what I replace 'mysite' with. I have tried the below

define('PERCH_RESFILEPATH', '/var/www/thecawdor/public_html/files');
define('PERCH_RESPATH', '/files');

but it says that the file is not writable. Any help would be much appreciated!
