I have an issue I know whats wrong but dont know what file to go into inorder to fix it.

when I add an item to my wishlist I get this error
1146 Table 'diecast_zc2.un_wishlists' doesn't exist
in:
[SELECT id FROM un_wishlists w WHERE w.customers_id=2 and w.default_status=1 ]

the issue is the table is called
'diecast_zc2.zen_un_wishlists'
not
'diecast_zc2.un_wishlists'

so what file do I need to fix this in?

thanks
