Adding feed process stops inputs updating

I'm trying to setup a new installation of emoncms on my local machine but can't get it to work.

I started out setting up the buffered write version from the 08/14 image which worked ok but when I realised it didn't have the kWh to kWhd processor I had to switch to the full version. I followed the guide in the buffered write branch to upgrade and thought all was well so then backed up my emoncms.org inputs and feeds to my local emoncms, but the inputs/ feed updates then came to a stop.

I then went through the whole process again installing the image and updating to the master branch etc but without downloading a backup from emoncms.org. This time the inputs where all updating but as soon as I tried to add a feed manually the inputs and feeds again came to a stop when using phpfiwa or phptimeseries feeds. When I tried to setup a phpfina feed I got a message as follows: ERROR: feed could not be created, undefined.

Any help sorting this would be much appreciated.
