+TROUBLESHOOTING
+
+The "unknown order/1/r" error indicates that you are trying to connect from a site 
+that is not known to the bank. This can for instance happen if you are testing from 
+a development environment and not connecting from the production site. 
+Which site is registered can be changed by the bank only. You can't do it yourself, 
+so you should call (+31)20-3832494 or mail them (internetkassa.cs@nl.abnamro.com)
