Hi there,
I think I’ve encountered the same problem. The (a tags surrounding) images get correctly added the necessary rel value but no lightbox pops open. From the js Console I see a jQuery error like “unrecognized expression: a[rel= lightbox[post-1234]]”.
Googling a bit took me here: http://stackoverflow.com/questions/15655154/unrecognized-expression-in-attributecontains-selector
I’ve solved by modifying plugin code (file lightbox-plus/class/filters.class.php) to generate rel values as
rel="lightbox\\[post-12345\\]"
This happens in a bunch of lines like this (173):
if (!$e->parent()->rel) { $e->parent()->rel = 'lightbox\\['.$postGroupID.$unq_id.'\\]'; }
This worked for me, I hope it may help someone else.
Cheers,

Thanks, Rash – unfortunately (or fortunately) that didn’t help me. Upon further investigation I discovered that my problem was caused by deleting a user. Restored the backup and upgraded to WP 3.8 – all is fine.
My apologies to Dan Zappone for erroneously blaming the plugin.
