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!

Disable Real MIME Check


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.

Mime Types Extended

Other plugins for this function, let you enter information to add any type, so that you aren't limited to the ones the plugin knows about. The absence of .azw and .azw3 formats, especially, make this useless for me.



Only supports the types it knows about.
