I'm using JW player plugin for wordpress (not wordtube) and while single files play fine, playlists result in the message "Task Queue failed at step 5: Playlist could not be loaded: XML could not be parsed or playlist was empty". See an example here:
I know I'm using the plugin correctly and that it is caused by a specific conflict between the plugin and my template which is called Pendulum, (http://themeforest.net/item/pendulum-premium-wordpress-theme/113557) since the JW player plugin works fine on other themes I activate. Furthermore, I have tested Wordtube (since disabled) and this works fine with playlists on the Pendulum theme, so it is something specific to the way the JW player is embedded.
When I use firebug, the only difference between my theme Pendulum, and any other theme in which playlists work is that my theme has 'index.php?xspf=true&id=32' rather than 'index.php?xspf=true&:id=32'
Can anyone point me in the right direction so that I can approach the theme developer with something concrete? I'm happy to experiment myself also but have no idea where to start.
