This looks like an issue with the data in your config file. Try moving it back into the couch folder and see if it works there, if not, then you'll need to have a chat with KK.

I agree with Daniel - there must be some error in the data you have entered in your config file.
Try moving the config file back to its original location (i.e. couch folder) and you should see the same problem here too.
Rectify the error and then move the config file as shown by Daniel.
Hope this helps.
