Hi,

when I created a new form it worked. Before that I always tried to update my existing one. That didn’t work.

But now I have it. Thank you

Hi, this was my code:

<?php
add_filter( 'upload_mimes', 'wpmudev_stl_gcode_add_upload_mime' );
function wpmudev_stl_gcode_add_upload_mime( $mime_types ) {
    $mime_types['stl'] = 'application/sla';
    $mime_types['gcode'] = 'application/x-gcode';
    return $mime_types;
}

I also tried your code. But the fact remains that I still cannot upload an STL file to the form.
