Default style - only getting the postbit text.
I am guessing that the error comes on that style because of the customised navbar.. it isn't really required because of the header and the sidebar. Reverting it (or commenting out the following line) fixes the php error...which occured everywhere (not just the gallery).
Code:
Content visible to verified customers only.
On a default (totally stock) style, the 'postbit' text is definitely still visible.
Not being an expert, I am still guessing that the $ is being stripped from the postbit variable somehow.
