Emoncms sync issue for newbie

Hi, hoping someone can help as I think i’m going mad. I’ve setup up the inputs and feeds and this is all working fine (getting the data online and local). HOwever, i don’t believe the sync is working as I get blank values, and nothing in Inputs or Dashboards. I’ve amended the config file with the read/write API and the Feeds and blank inputs appear. When I originally setup the system then realised I’d duplicated things, so deleted the online inputs and feeds, and just kept the local versions. I believe I may have caused an issue when doing this as I now get an error when looking at the log (See below)

Running: 10.8.5
Hopefully it is a simple fix.
