I made changes from dashboard but they are not live on my blog

Superblog is a slightly different technology when compared to other blogging platforms.
You need to click the ‘Deploy Site’ button after you make changes to your blog or posts or edit anything.

So, make all the changes you want in the dashboard. Maybe update a post, add a tag, change settings and after all your edits, just click ‘Deploy Site’.
