Hi,
I changed the index.php file to use this instead: $conf->IP = dirname( dirname( __FILE__ ) ); and I found a function in the 1&1 FAQ (http://faq.1and1.com/scripting_languages_supported/php/8.html) that stores PHP error messages from the 1&1 server.
Here are the error messages:
08/09/2004 18:29 "/homepages/27/d8842wxyz/htdocs/wiki/includes/DefaultSettings.php: 21" (Notice) Undefined variable: wgCommandLineMode 08/09/2004 18:30 "/homepages/27/d8842wxyz/htdocs/wiki/includes/DefaultSettings.php: 21" (Notice) Undefined variable: wgCommandLineMode 08/09/2004 18:30 "/homepages/27/d8842wxyz/htdocs/wiki/config/index.php: 807" (Notice) Undefined property: DBmysql4 08/09/2004 18:30 "/homepages/27/d8842wxyz/htdocs/wiki/includes/Database.php: 106" (Warning) mysql_connect(): Access denied for user: 'root@217.160.226.22' (Using password: NO) 08/09/2004 18:30 "/homepages/27/d8842wxyz/htdocs/wiki/config/index.php: 420" (Warning) mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource
Does this give any more clues as to what's going wrong? What is that about 'root' - I didn't fill that in on the form (I supplied the database login).
