We're having the same issue. Had to comment out this as a temp fix:

https://github.com/osTicket/osTicket/blob/develop/include/class.forms.php#L3975-L3977

jothie , we had the same issue with saving emails on Mac vs windows. The difference was that Mac uses .eml files which work ok, Windows uses .msg, which does not work.

I'm not sure if you're having the same problem.

we have the same issues after updating to v1.17.3, we used version 1.17.2

solved by activating the fileinfo in the php manager

The problem ist that $file['type'] and FileObject::mime_type($file['tmp_name']) do not return the same result.

in case of a zip-file:
string(28) "application/x-zip-compressed"
string(24) "application/octet-stream"

Yes, I have seen this with someone else, however I’m unable to replicate this with ZIP files in my instance. What version of PHP are you using? What browser are you using? What OS are you using when uploading the file?

Cheers.

Ugly Fix:

class.forms.php replace the function

static function isValidFile($file) {
    // Make sure mime type is valid
    #var_dump($file['type'], FileObject::mime_type($file['tmp_name']));die;
    #if (!empty($file['type']) && strcasecmp(FileObject::mime_type($file['tmp_name']),
    #            $file['type']) !== 0)
    #    return false;
    // Check invalid image hacks
    if ($file['tmp_name']
            && stripos($file['type'], 'image/') === 0
            && !exif_imagetype($file['tmp_name']))
        return false;
    return true;
}

If I were you I’d install a vanilla osTicket and retest there. We do not support the German version. They make customizations to the code so it’s not official osTicket.

Also, yes, I tried your file and worked without issue.

Cheers.
