I installed the Mobile style and I think this has caused a problem with this mod. The funny thing is though, when I switched on the HTML Template comments via the Settings it fixed the issue by putting in a malformed 'list' tag.
Anyone else experienced this? I'm using 4.1.10.
Addition: I've just copied and pasted TiKu's updated version and now it appears to have fixed the display issue when HTML Comments were enabled so
thanks for the fix TiKu!! 
Just to add that now the opposite happens whereby with HTML Comments active this mod appears to experience a problem though it's not much of an issue now.
