Im trying to edit the sidebar block templates, I have created a custom block to use the "block_html" template which all works and displays fine, I want to edit things a little so I have tried editing the "block_html" template to make a few changes but nothing appears to change in the sidebar, I even deleted the contents of the "block_html" but my custom block still shows even though I deleted the template..
So does anyone know what im doing wrong, and how to edit the sidebar templates?
