Thread:Project:Support desk/File uploads aren't working correctly. Image not found after upload.

My Wiki is private, otherwise I'd link it. I'm using ImageMagick. It's version 6.7.7 installed via "sudo apt-get install mediawiki" yesterday.

Product Version

MediaWiki 1.23.1

PHP 5.5.9-1ubuntu4.3 (apache2handler)

MySQL 5.5.38-0ubuntu0.14.04.1

Error I see in thumbnail for newly uploaded file:

Error creating thumbnail: /bin/bash: /w/extensions/ImageMagick: No such file or directory

Error code: 127

When I click the file, it says "Not found". The directory has 775 permissions and is owned by www-data. I'm not sure what the issue is. :/ Google and other people's solutions haven't helped.
