Why are my PHP sessions not working properly?

The path to sessions must be set manually in our Cloud infrastructure in order to work properly. You can specify the path by adding the following code to your .htaccess file, substituting the correct path for your site:

php_value session.save_path /mnt/stor1-wc1-dfw1/123456/www.domain.com/web/sessions
php_value session.save_handler files
