Images not displayed in wiki pages after upgrade

I recently upgraded a Mediawiki 1.18 installation to version 1.23 following the guide. All of the data and accounts seem to have transferred. In order to upload files again, I had to run the following:

sudo chown -R www-data images
sudo chmod -R 755 images/

I can now upload images. At Special:ListFiles, I can see all of the uploads, and images are displayed properly, both at full-size and as thumbnails. However, when I include them in a page, they are not rendered as images. For example, File:Margin_padding.png when included by [[File:Margin padding.png]], is rendered as the following:

File rendering

Most of the similar sounding issues I've found are due to bad mime-type detection, but according to mediawiki and the PHP interactive shell, the example image is image/php. I have the same symptoms for images uploaded before the migration and after. Are there any settings that could result in this behavior?

What solved it for me was adding this in LocalSettings.php:

$wgHashedUploadDirectory = true;

This setting was probably already set to true on first installation but went missing (so false?) after an upgrade.

Since this determines where and how images are uploaded (into images/ in bulk or into subdirectories of images/) changing it on an already configured wiki -- i.e. with images already uploaded -- will break it and the wiki will look for images in the wrong place / using the wrong method.

In the LocalSettings.php file from version 1.18, I had $wgUrlProtocols[] = "file:";. As of version 1.20.2, this breaks image embedding. The solution is to use file:// instead.

$wgUrlProtocols[] = "file://";
