When I created the sql database and the user, my host obligates a prefix and underscore before the names. (ex: database: liceoang_news user:liceang_admin).
When I test the connection in the second step of the intallation it shows this error message:
Connecting to server:Access denied for user 'liceoang'@'localhost' (using password: NO)
in red.
I think that N13 dont accept names with underscore, I don't know that, but what can I do to use those names?
