[RCU] Database error

[Meaulnes Legler @ roundcube]

hello

I installed Roundcube's new version 1.3.4 from the previous version 1.2.4 the on a BlueOnyx server. Since then, I can't login at http://server/roundcube/, I get instead of the login form the error

*DATABASE ERROR: CONNECTION FAILED!*
Unable to connect to the database!
Please contact your server-administrator.

I am actually the server administrator with root access, but have no idea how to proceed here...

Anybody knows how to fix/reconnect this MySQL database?

Thank you and best regards
