Got the plugin up and running. Whilst I was developing the WP site it had a longer URL. Now I have applied a domain name so http://tvcm.co.uk/mela2014/?p=5332 is now http:/boromela.co.uk/?p=5332 - however I've also smartened up the Permalinks to the post I'm broadcasting to twitter is actually http://boromela.co.uk/final-test/ and whilst http://tvcm.co.uk/mela2014/final-test/ might find it http://tvcm.co.uk/mela2014/?p=5332 does not.
I don't want to change the permalinks back as I have other issues depending on the URL's being as they are. I've tried uninstalling/reinstalling the plugin to no avail.
what do you suggest?
