Have you tried importing CSV file to WordPress and got the message ” “Sorry, this file type is not permitted for security reasons” ? If that is the case , first thing to note that this is not fault of the plugin through which you are attempting to import the CSV file. This is WordPress error ! Here is why it happened and what is the solution ?
WordPress filters the file types (MIME types) which users can upload through the media uploader and other areas of the dashboard. See the Uploading Files documentation in the WordPress for more information on which files are allowed.If you try to upload a file which is not allowed, you will be presented with a “Sorry, this file type is not permitted for security reasons” error message but this error can be fixed easily if you have to upload a specific file which is not allowed.
What are MIME types?
MIME stands for Multipurpose Internet Mail Extensions. MIME types are used by browsers and other internet devices to determine the type of content associated with a page. For instance, if you have a CSV file or .png file and a .jpeg file on the page, the browser would know by their MIME types to treat first file as CSV whereas other two files as images rather than videos.By default, WordPress has a list of registered mime types stored in wp-includes/functions.php. Using the wp_get_allowed_mime_types() function you can get a list of MIME types WordPress recognizes. These files are the file types recognized by WordPress.
So if the file you are uploading is not added in the list of MIME type recognized by WordPress, the error message ““Sorry, this file type is not permitted for security reasons” will appear .
