Disable Real MIME Check

by Sergey Biryukov

Version: 1.0

Description

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 Trac ticket.

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!

Installation

Upload disable-real-mime-check folder to the /wp-content/plugins/ directory.
Activate the plugin through the ‘Plugins’ menu in WordPress.

Problem solved! Worked for me > WP core at 6.3

By danfeather on August 25, 2023

This plugin solved a problem that had me at an impasse. No matter what "solutions" from WooCommerce and other forums/posts I'd tried, I was unable to import a CSV or Tab-Text file to update details for my products. I installed this plugin and, voila!, success. It's a one-trick pony, but it's the thing I needed. Thanks! Sergey! (WordPress 6.3, WooCommerce 8.0.2)

works in WP 6.1 and WC 7.5

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!

Still works as of 2023

While some files are transferred, I get the following warning: “Sorry, you are not allowed to upload this file type.”
It seemed to work when removing HTML from my .csv file. However, sometimes it is preferred to keep HTML when importing.

This plugin fixed the issue.
