Issues with Portfolio gallery

Hi there,

I’ve just purchased the multi site Portfolio plugin and trying to setup a lightbox gallery but it is not aligning properly and no option to make it centred too. I’ve tried all kinds of settings that i can see but it is still not working. Also, the categorisation button doesn’t work too.

Can you please advise what is wrong?

Here’s the test link that i’m working on.
