[Plugin: NextGEN Gallery] on upgrade, images no longer open in lightbox

A first step could be to take a look at ‘Gallery’ > ‘Options” > ‘Effects’, and see what the ‘JavaScript Thumbnail effect’ is set to. It might be set to ‘none’.

Hey the same thing is happening to me except it is a new installation. It doesn’t happen all the time though. Seems like it only happens the first time you click on an image and only if it is not the first. If you then click back and click on any other image it does the effect selected. It is currently set to use the shutter effect. I’ve had to switch it off now because it is for a client. Please help!
