I’m having the same problem.
Using Pinboard on a couple of web sites of mine and absolutely LOVE the theme. Thank you for making it available!
In one of the sites I’m having the same problem: the Customize page is completely blank and clicking on any menu on the left simply does not do a thing.
(my other site is OK).
I have completely uninstalled the Pinboard theme and reinstalled it but this did not help.
Can you please assist.
