I think there is a misunderstanding. This has nothing to do with the lytebox. I can not get the tabs activated on the font end. To make more clear I insert screendumps. The url is:
www.siteinontwikkeling.nl/rdta.
I believe I activated the Joomla module in the right place... see enhancement. I can also grant you access if you want.
In tabs frontend demo.jpg you can see what I want...
Best regards,
