playlist playing only one song at a time then stopping

Hello

I am using LMS on an Antipodes music server.

Today I was playing with some plug-ins to see what they did.

But now I have somehow changed some setting so that the playlists will only play one song then stop. This is true if I load a whole album or individual tracks. When the track ends, instead of going on to play the next track in the list (as it did before i fiddled) it just stops.

Is there some setting I need to change to fix this? I can't find it. Apologies if this question is very basic.

Cheers
