I've just installed Lightbox Plus ColorBox and I'm having a simple problem.
I've checked the settings, I've used the Demo/Test and works perfectly.
The problem is whenever I add a new image on a post, the rel="lightbox[postID]" does not automatically add, and therefore, the plugin doesn't work.
I've added the code manually and the imagen works fine as I configured it.
Why doesn't the code automatically adds? The option "DO NOT Auto-Lightbox Images" is NOT checked.
Help please? Thanks.
