mime file type validation on wiki

Question

I am running a private MediaWiki version 1.35.1 on Ubuntu Mate. I added a new file extension, 'cev', to my LocalSettings.php but when I try to upload a file it gives me this message:

So, I went to this page and down under Mime Type validation it says there are 2 files in the Mediawiki includes folder that can be customized to allow/ignore that error. Well, a "broken link" note on that page seems to indicate that the file MimeMap.php under /includes/libs/mime is the one to modify.

So, how do i modify MimeMap.php so it either ignores .CEV files or otherwise accepts them without the error message?

To support extra mime types for uploads on your wiki, you can use the MimeMagicInit hook since MediaWiki 1.24.

For example, to recognise .md files as text/plain for Markdown:

// Recognise the extension
$wgHooks['MimeMagicInit'][] = function ( MimeAnalyzer $mime ) {
    $mime->addExtraTypes( 'text/plain md' );
};

// Allow it for new uploads
$wgFileExtensions[] = 'md';

I've also updated the MIME type detection page on mediawiki.org with this, and more information.

Did you already try https://www.mediawiki.org/wiki/Topic:Ps6zng4e6b00rsor

$wgVerifyMimeType = false;
$wgStrictFileExtensions = false;
$wgCheckFileExtensions = false;

There is also a strange workaround for some file types:

$wgAllowJavaUploads = true; // Solves problem with Office 2007 and newer files (docx, xlsx, etc.)

https://www.mediawiki.org/wiki/Manual:$wgAllowJavaUploads

seems to help in some cases.
