With the upgrade to WordPress 4.7.1, some non-image files fail to upload on certain server setups. This will be fixed in 4.7.3, see the <a href="https://core.trac.wordpress.org/ticket/39550" rel="nofollow ugc">Trac ticket</a>.
In the meantime, this plugin is a workaround that disables the recently introduced strict MIME check to restore the upload functionality.
Don’t forget to remove the plugin once WordPress 4.7.3 is available!

IDK if it's a bug in WC or something, but I can't upload .csv files, had to hook this in so I can update some prices... very helpful!


works in WP 6.1 and WC 7.5

Restores the ability to upload non-image files in WordPress 4.7.1 and 4.7.2.

Add more files extensions with a new field in your Medias Settings.
<a href="http://irz.fr/add-more-files-extensions/" rel="nofollow ugc">You can check the dev page</a>
You just need to insert your extensions in <code>Settings > Medias > Uploading Files</code> separate by a space (ex : ‘exe pdf rar’), and the plugin does the rest.
This plugin is in french but the translation in english is in progress.
