The BibTeX extension doesn't work anymore. Though it never really worked, so it's not much of a loss. I should probably build a replacement but I don't have the time right now.
====Upload Multiple Files====
Although the Upload multiple files extension installed fine, it is unmaintained and seems to have an issue. I removed its line from LocalSettings.php and deleted its extension directory.
I then installed [https://www.mediawiki.org/wiki/Extension:SimpleBatchUpload Simple Batch Upload] using a tarball:
in mediawiki/installs
wget https://github.com/ProfessionalWiki/SimpleBatchUpload/archive/1.6.0.tar.gz
tar -xzf 1.6.0.tar.gz -C /var/lib/mediawiki/extensions
mv /var/lib/mediawiki/extensions/SimpleBatchUpload-1.6.0 /var/lib/mediawiki/extensions/SimpleBatchUpload
In LocalSettings.php:
wfLoadExtension( 'SimpleBatchUpload' );
$wgSimpleBatchUploadMaxFilesPerBatch = ['*' => 10,];
I had previously added Special:MultiUpload|Upload multiple files to http://www.edegan.com/wiki/MediaWiki:Sidebar. I replaced it with a link to [[Special:BatchUpload]].
