I\'m unable to upload CSV file on the WordPress website
error: Sorry, this file type is not permitted for security reasons
Check the following
I believe, everything is clearly mentioned in the error and you highlighted that too : This file type is not permitted for security reasons
To fix this, add this code in wp-config.php
define('ALLOW_UNFILTERED_UPLOADS', true);
Or you can also use a Plugin called "WP Add Mime Types", And add ONLY types which you want to be added
