The 'Display using a custom template file' checkbox is disabled for me. I know that this should be enabled by moving/copying the yarpp-templates folder into my theme folder - but I've tried this (both moving and copying) and it's still not enabled.
I'm using version 3.3.1 of the plugin, but also tried the latest dev version (linked yesterday from here http://wordpress.org/support/topic/yarpp-giving-me-a-blank )
(Related - what I'm actually trying to do is amend the code output by the widget. Is this actually dealt with in the custom templates?)
Any help appreciated!
