Spot on. I was using BlueMCE2. Now swapped back to just Blue and it works fine. I still get the 'playlists' button under the 'Main Menu' button. Is this by design?
nah its not by design, if you edit the config.xml file you'll see a section in the pluginssettings/myvideosplugin part for the menu, just delete that entire thing and go into the config, you should then be able to turn off the playlist feature. i think its just a bug i missed.
