Yep, I need to fix that, gonna work on that now.
Hey, ok so I re-checked now and maybe it's because you don't have the latest version of the lightbox addon. The lightbox addon's latest version is 1.1.8. Maybe you don't have the latest version because all the addons were also affected by the update service breaking. I wrote an email to everybody who had bought an addon and explained how to install the new versions, maybe u didn't get that email.
I'm sending the latest lightbox addon version to your email address! Please try that version and then let's see if the problem persists.
