I just upgraded my tiger server. When I go to the dotProject page with a browser, I now see this:

Warning: mysql_connect(): Access denied for user 'dp_user'@'localhost' (using password: YES) in /Library/WebServer/Documents/dotproject/lib/adodb/drivers/adodb-mysql.inc.php on line 327
FATAL ERROR: Connection to database server failed

MediaWiki is also missing in action. When I log into mySQL, the dotProject database is no longer there!

Does anyone know what is going on?

Does anyone know what is going on? Hmm... can't say that I do, as my upgrade to Tiger didn't do any harm. I'm sure you'll find that it's something simple (or at least I hope so)

Does anyone know how I would go about restoring, or trying to find the mySQL database files?

The MySQL stuff is normally under /Library/MySQL with the data being there under .../var.
Did you try a brute force approach like doing find / -name mysql* -print as root in Terminal to see where they ended up?
I am not very MySQL-savvy and use CocoaMySQL for MySQL admin tasks, may you should give it a try.
Good Luck

I had the same problem with Wiki failing after upgrading to Mac OS X Server 10.4. The solution is not quite as obvious. Under 10.4, there's a new program called:

/Applications/Server/MySQL Manager.app

Open this up and authenticate by clicking on the little lock in the lower left hand corner. Then, press the Stop button to shut down MySQL (if running). Then, check the "Allow Network Connections" checkbox. Finally, press the "Start" button to get it going again.

That should get your Wiki (and dotProject) services working again.

P.S. How did you get the GD graphics library working on 10.3.9? I can't find a good install yet... :) Is there a dmg I can use?
