'Sorry you are not allowed to edit this item'.

Hi, I've followed the instructions closely re setting up this plugin on both my sub domain and main domain sites. On both sites I have completed the post types, taxonomies and custom fields. As I don't feel comfortable connecting to my site using ftp and creating a single.php template I've gone into setting/create a template. Every time I then try to create a post under the custom setting that appear in my wp menu bar I get the message 'Sorry you are not allowed to edit this item'. What am I doing wrong? Is there any way I can pay someone to configure this plugin for me? I'm not a developer, and I'm really stuck. Thanks. :grimacing:
