Fatal, non-recoverable error...

Hi guys, I seem to be getting a lot of errors when trying to connect to pages at the moment and I'm also seeing a lot of ?>?>?>?>?>?>?>?>?>?>?>?>?> which is doing my head in trying to think how to get rid of it. The message I often get I've copied below and I've already spoken to my hosting company (Streamline) who told me to ' Within your connection script try replacing the hostname from 'mysql9.streamline.net' and replace it with xxx.xxx.xxx.xxx but I've no idea where they mean when they say within the connection script. Also these ?>?>?>?>?> seem to come up at the top of the error page and annoyingly on the top line when trying to put in a member's name to whisper to. If anyone's any idea on what I can do I'd be extremely grateful! A fatal, non-recoverable error has occurred Technical information (for support personel): Error Message The connection to the database failed: Affected Elements MySQL.OpenConnection(); The error occurred on or near: Unknown MySQL server host 'mysql9.streamline.net' (2) For additional support documentation, visit the Lussumo Documentation website at: lussumo.com/docs
