When showing a blog post on the frontpage, i want some metadata to be shown underneath the title (Category and author), and when entering the blog post, i need more info. Where do i choose this/add this?
Go to template. Click on your default template and select the desired parameters.
If you want to display blog info such as date, category, author etc you may set it here in your joomla backend > easy blog > settings > layout > general shown here in this screenshot http://screencast.com/t/nr8WrsA0
