restoring wordpress database from mysql dump

Question

Is there way to correctly restore a Wordpress database from an older mysqldumb file (.sql)? I can't remember the wordpress version, but it wasn't lower than 3.4.2.

At the moment whenever I try to restore like this:

mysql -u blogadmin -p new_db < old_db_dump.sql

I get no error (at least no error is output) and then I get a white first page on my blog.

Answer 1

White first page usually means that there is a php error during rendering of this page. Try to enable php error_reporting (or error logging) and see these error messages. Depending on error messages you can try to fix wp scripts version or apply updates to your db.
