[ale] Tiki problems

[David Corbin]

I have a web site for an open source project that I'm "somewhat responsible 
for" that uses Tiki.  I inherited this, and unforunately, I know virtually 
nothing about it or PHP.

"Suddenly" I get these errors...

Warning: main(DB.php): failed to open stream: No such file or directory 
in /home/groups/p/p4/p4eclipse/htdocs/tiki/db/tiki-db.php on line 4

Fatal error: main(): Failed opening required 
'DB.php' (include_path='.:/usr/local/lib/php') 
in /home/groups/p/p4/p4eclipse/htdocs/tiki/db/tiki-db.php on line 4

Obviously, it can't find the DB.php file on it's path.  But I have no clue 
where DB.php comes from.

If anybody would like to help me here, or even just fix it for me (grin), 
please let me know.
