fixing website translations

[Graham Percival]

I've been seeing these warnings for months:
Processing web site: [cs]
WARNING: Unable to find node 'Řešení potíží' in book usage.
WARNING: Unable to find node 'Proč se mění skladba?' in book
usage.
Processing web site: [de]
Processing web site: [es]
Processing web site: [fr]
Processing web site: [hu]
Processing web site: [it]
WARNING: Unable to find node 'Text editor support' in book usage.
WARNING: Unable to find node 'Troubleshooting' in book usage.
WARNING: Unable to find node 'Why does the syntax change?' in book
usage.

could somebody fix them?

Cheers,
