[Plugin: Lightbox plus Colorbox] 500 Internal Server Error

Hey everyone. I am hosting a site on GoDaddy, and since upload a few days ago from my localhost, I hadn’t been able to solve the 500 Internal Server Error. I spoke with them on the phone, did their suggestions, and didn’t have any luck. Finally today I saw on another post on here a suggestion to disable all plugins. Did that, issue resolved. Started enabling 1 by 1, and everything worked until I re-enabled Lightbox plus Colorbox. 500 error popped up again, but as soon as I disabled it, error was gone.

Anyone know why this would happen, and what I can do to enable the plugin but not cause the 500 error?

Thanks for your assistance!
