wmv video upload not allowed

[Marie29200]

Hello

I would like to upload a wmv video file in my product page but there is a "server_error".

I think that the extension is not allowed. So I have added it in the file /admin/filemanager/config/config.php (prestashop 1.7.6.7)

$ext_video = array('mov', 'mpeg', 'mp4', 'avi', 'mpg', 'wma', 'flv', 'webm', 'wmv', 'wma', 'mpeg'); //Video

But it still does not work.

Can you please help me ? I have a lot of wmv videos to upload, it would take a lot of time to convert each of them.
