From your first post, I understood that both MySQL
belong to you,
right?
No, I just have full access to the server I want to restore mediawiki to.
The server to back up the database has only phpmyadmin for exporting.
That's the main problem.
I solved it by telling my provider to make a mysqldump (with that latin1
option) by hand (and they luckily do so).
But I think, that to this problem should be referred on an offical "How
to backup" page at the mediawiki documentation.
Cause surely a lot of people do backup of mediawiki by exporting via
phpmyadmin and are not aware of, that if they had to restore the
database, there is trouble preprogrammed.
