...when I attempt to add a Z MySQL Database Connection to a folder, I get "Invalid connection string" -- no matter what the connection string....

Problem solved. It turned out there was a line of commented-out diagnostics on the page that reported "Invalid connection string." That let me know the problem was an inability to connect through the socket. Checking that, I discovered that the RedHat default install has 0700 permissions for the directory containing the MySQL socket. Changing that to 0711 cleared up my problems. _________________________________________ Steve McMahon, SunType Publishing Systems steve@suntype.com voice & fax: (530) 757-7682 http://www.suntype.com
