Mysql runs at the webserver (or at a database server networked to the webserver). Any errors you see are generated there.
All you can do: send an email to their webmaster with a complaint. He's the only one to can repair it (or have it repaired).
Hope this helps.
I went to a web site for Look Cycles in France and received numerous messages regarding 'error in mysql, file not authorised', etc. Does this mean I have to have mysql loaded to view the web pages? Just interested. I could view somm, but not all pages. I went to mysql site, but downloads were not for windows.
