Webp File type not allowed

Hello @charlotte83 ,

1. Make sure to manually add filetypes:webp to the [mfile] shortcode parameter.

For example: [mfile uploader-xxx filetypes:webp|jpeg|jpg|gif|png|pdf|docx|odt|doc|heic|zip]

Or you can do via cf7 form tag generator. (see screenshot below)

If you have already added the (webp) extension but it’s still not working, it might be related to mime types.

Try to add the code below in your child/theme functions.php file.

function add_webp_mime_types($mime_types) {
    $mime_types['webp'] = 'image/webp';
    return $mime_types;
}
add_filter('mime_types', 'add_webp_mime_types');

2. For max size limit, if not set the default is 10MB so you should configure it manually to match the max limit in your WordPress media library.

To do that, you will need to add limit:BYTES_FORMAT parameter in [mfile] shortcode, or you can configure it using CF7 form tag generator.

Example: [mfile uploader-xxx filetypes:webp|jpeg|jpg|gif|png|pdf|docx|odt|doc|heic|zip limit:104857600]

Note: limit should be bytes format you may use MB to Bytes converter in Google (ie: 104857600 = 10MB)

Thank you so much. Have a great day.
