oops, sorry for that, I misunderstood/misread the log
as for the capitals, just to be sure, do you have :
the mediawiki extension in : somepath/mediawiki/extensions/FCKeditor/FCKeditor.php somepath/mediawiki/extensions/FCKeditor/someotherfiles
the fckeditor in a sub-folder : somepath/mediawiki/extensions/FCKeditor/fckeditor/fckeditor.php somepath/mediawiki/extensions/FCKeditor/fckeditor/fckeditor_php5.php somepath/mediawiki/extensions/FCKeditor/fckeditor/someotherfiles
in your extension directory ? or another structure ?
(FCKeditor.php and fckeditor.php are different files and you should only include FCKeditor.php in LocalSettings.php)
