Why are you trying to create wikipages that are so large? Also, you're looking in the wrong place. The error doesn't come from uploading a file but from editing a wikipage. The message is longpageerror (which you can see at http://mizugadro.mydns.jp/h/index.php/MediaWiki:Longpageerror) and is displayed when you attempt to create an article longer than $wgMaxArticleSize (see: https://www.mediawiki.org/wiki/Manual:$wgMaxArticleSize).
Before increasing the size, though, you should think about how many wiki pages you anticipate being that long.
