I just updated to WordPress 3.6 and I updated Efficient Related Posts to 0.4.0 at the same time. Now the plugin isn't working on my site at all. There is no error message - it's just not showing on the live site (it WAS working today before I updated everything).
First I tried "Building Relationships" - it said that was successfully completed but the Related Posts still weren't showing on any of my pages. Next I deleted the plugin & re-installed it. Nothing. I re-built the relationships. Still nothing.
I've used this plugin successfully for months - I don't know what is wrong? Anyone else having problems?
