OK, there was a minor error with the code for "Vampire: the Masquerade".
// SMFShop
echo $tab1, $ca== 'shop' ? '1' : '2' , '"><a href="', $scripturl, '?action=shop">Shop</a></td>'
Should have been:
// SMFShop
echo $tab1, $ca== 'shop' ? '1' : '2' , '"><a href="', $scripturl, '?action=shop">Shop</a></td>';
I've edited this on the Wiki. Please try it again, it should work this time. Also, note that the first edit for that theme has a comma at the start of it.
