Hi !
I’ve similar problems with lightbox 2 on latests wordpress series, and I now only one thing you could help.
I installed it 2 times on different servers and on one work, but on second “nothing happens” like you described. Seem to be the problem will be in a server setings, or a javasript settings?
After finishing uploading the image, and putting it on to one post I switch for the HTML code and there’s missing the /a href/ part, just only an /img src/….
Know anybody more?
