Thread:Project:Support desk/How do i install multiupload?/reply (18)

The error reads

require_once(".../extensions/MultiUpload/MultiUpload.php"): Failed to open stream : No such file or directory in .../LocalSettings.php on line ...

So...can you please upload the files of the MultiUpload extension to your server? MediaWiki.org will give you a tarball and you are expected to extract its contents so that you afterwards do have a directory MultiUpload/ inside your extension folder and inside that directory the file(s) of the extension, among them the file MultiUpload.php.

Template:ExtensionInstall could in fact tell more clearly that you are expected to extract the tarball on the server. Downloading and placing the files in the directory as the template currently says is not enough.
