I ahve searched through the archives and have not managed to find a solution to this yet.
I am just in the process of moving my wiki to a new server. Everything ran fine on the old box but when I install on the new one I get the following.
MediaWiki 1.5.6 installation Please include all of the lines below when reporting installation problems.
Checking environment... PHP 5.0.2: ok PHP server API is cgi-fcgi; using ugly URLs (index.php?title=Page_Title) Have XML / Latin1-UTF-8 conversion support. PHP is configured with no memory_limit. Have zlib support; enabling output compression. Neither Turck MMCache nor eAccelerator are installed, can't use object caching functions GNU diff3 not found. Couldn't find GD library or ImageMagick; image thumbnailing disabled. Installation directory: D:\home\Default\xxxxxxxxxxx.com\htdocs\wiki Script URI path: /wiki Warning: $wgSecretKey key is insecure, generated with mt_rand(). Consider changing it manually. PHP is linked with old MySQL client libraries. If you are using a MySQL 4.1 server and have problems connecting to the database, see http://dev.mysql.com/doc/mysql/en/old-client.html for help. Connecting to sf on localhost as root...failed with error 1251: Client does not support authentication protocol requested by server; consider upgrading MySQL client. Something's not quite right yet; make sure everything below is filled out correctly.
and then further down
Database config MySQL server Couldn't connect to database
I have seen a post that suggets upgrading PHP so I tried 5.1.2 but this broke so many other things that I don't think it is worth it.
I have also seen various posts reagrding authentication and I have done the set password thing in MySQL - this didn't help either.
Anyone have any ideas how I can take this forward?
