[Plugin: NextGEN Gallery] Singlepic doesn’t work properly

I’m having a similar issue. Inserting an image via singlepic works fine for one image, but attempting to insert a 2nd image via the same method only displays the code (e.g. [singlepic id=146 w=250 h=180 float=] )

I disabled caching of single images as per another post here, but without effect. We’re using WP 2.8.2 & NGG 1.3.5.
