1 - COPS is in /var/www/cops
2 - Calibre data is in /media/cloud/calib
re/books -> this worked (?)
3 - multiple directories are in /media/cloud/calib
re/[different-sub-directories] -> this did not work
In /var/www/cops/config_local.php did you set it up like this?
Code:
$config['calibre_directory'] = array (
"Books 1" => "/media/cloud/calibre/books_1/",
"Books 2" => "/media/cloud/calibre/books_2/",
"Books 3" => "/media/cloud/calibre/books_3/",
"Books 4" => "/media/cloud/calibre/books_4/"
);
Pay attention to the comma's and the trailing "/"'s.
If you set it up like this, do you still get the error in checkconfig.php?
I have more or less the same setup, so it should and will work.
