[Mediawiki-l] Upgrading from MediaWiki 1.4.5 to 1.6.7 -- Problem resolved....

[khuffman at NGS.ORG]

I realized my error almost as soon as I sent the email -- user error (me, 
specifically). I had uppercase letters for the subdirectory that I was 
referencing while my upgrade script was looking for an upper/lowercase 
subdirectory. Hence, the previous message of "No input file specified." 
So, seems as though the update.php file worked fine for me on version 
1.4.5 as well. Thanks, Karen
