Do you have a link to your (broken) site, so we can have a look?
Did the database upgrade perhaps corrupt the blog entries? Have you made a database backup before you upgraded and can you try to put this backup back on the new database install?

Thanks for asking:

If I go there with Mozilla, I get

================================================
Additional information about this error:

MySQL error!

Error establishing a database connection!

(Client does not support authentication protocol requested by server; consider upgrading MySQL client)

1. Are you sure you have typed the correct user/password?
2. Are you sure that you have typed the correct hostname?
3. Are you sure that the database server is running?

================================================

I can get in to the database using the username, database name and password that b2evolution is configured for, but I can't get in through this URL. If you know which MySQL client they are referring to, that would help.
