Seems to work for me, like all the other Lightbox Effects. And also work at one of my testsites with WP 3.7 alpha.
But as Photocrati have stated in another thread/message, currelty lightbox effects work only with galleries, not other images (like images from Media Library) – at that was not fixed for 2.0.2 beta (why I did not even bother to use it…).
I am having the same problem & am not sure why. I have used this plugin before but this is the first time I have installed it on version 3.6 WP. JL – no idea what that instructions means but if someone has any instructions and idea how to fix please help.
Initially I thought changing the theme might help but it didn’t.
I am stuck as I can’t find any other galleries that work really easily & right now am putting photo’s in by hand !
As in legacy versions of NextGEN Gallery (v1.9.x), you will need to install an additional lightbox plugin like Jquery lightbox or Lightbox plus if you are selecting ‘Lightbox’ under Lightbox Effects in the settings. You won’t have to install an additional plugin if you choose the ‘fancybox’ effect or thickbox or one of the others available in v2.0. Now it could be that the lightbox plugin you were using has stopped working/ hasn’t been updated to be compatible with v3.6, so you may need to try another lightbox plugin and remove the one you were using.
I just double checked that things are working well in v3.6 and as @vesat pointed out, in the latest beta of WP 3.7.
