[]c:inetpubwwwrootubbthreads/config.inc.php is not writeable
To use the option from the admin menu, you need to set the permissions on config.inc.php and theme.inc.php to 666. You can do that from an FTP program (there should be an option to change permissions). In some programs the files have r, w, and x instead of numbers. In that case, 666 is rw-rw-rw- . If you telnet, I believe you can use the command chmod 666, but I'm not exactly sure of the syntax, because I haven't used telnet in way too long.
Your paths/urls will probably be similar to this:
// Url to the main UBB.threads php install
$config['phpurl'] = "http://www.yourdomain.com/ubbthreads";
// Absolute Url containing the images
$config['images'] = "/ubbthreads/images";
// Path to your images directory, needed for calculating image sizes
$config['imagepath'] = "/usr/local/plesk/apache/vhosts/yourdomain.com/httpdocs/ubbthreads/images";
// Url to your stylesheets directory
$config['styledir'] = "/ubbthreads/stylesheets";
// Path to your UBB.threads php install
$config['path'] = "/usr/local/plesk/apache/vhosts/yourdomain.com/httpdocs/ubbthreads";
// Path to your stylesheets directory
$config['stylepath'] = "/usr/local/plesk/apache/vhosts/yourdomain.com/httpdocs/ubbthreads/stylesheets";
(The paths are going to be worded much differently, I'm sure, but that's the direction the slashes should go.
