Hi Mark Foster,

I am sorry for the late reply for this. It seems like you have hit this error :

Fatal error: Call to a member function hasCustomFields() on boolean in ../administrator/components/com_easyblog/includes/composer/composer.php on line 288

This error occurred because you did not set any default category. I have make a default category for you,and the composer is works fine now. Please have a try

To change the default Category you can:
1. Click Component->EasyBlog->Categories-> star the Category as a default Category
Refer this screenshot : http://screencast.com/t/YQ4YTjSC3eDv

Have a nice day ahead Mark
