The setting use_flash is already configured false. It won't help.

I had a lot of difficulties with getting access and permissions. These worked their way in a lot of process. The main fix was to allow everyone and everywhere. Don't know if that's supposed to be named a fix.

Anyway, is there a way to allow spaces or write my own code to replace the characters (where to place the code?)

I have the same problem with spaces in filenames as RdeWilde here. I have flash upload disabled and version 3.0.2

The uploader is complaining about "Filename is Invalid" when I try to upload filnes with spaces in the filename.
I is easy to remove spaces in the filename by hand but it shouldn't be necessary. It should be removed automatically. My customers get all freaked out whenever they see a error screen and doesn't care to find out what they need to do.

I hope you could have a look at this for future versions and point me to the js file that handles filename uploads so I may try a fix myself.

That seemed to do the trick. But still. This is allowing spaces in filenames on the server! Thats breaking a golden rule in server filesystems isn't it? It works in my browser but it could result in some strange urls like /my%20picture.jpg that may be bad for some scripts.

So instead I made a hack in /pages/im/js/upload_dialog.js after line #288 that changes all spaces to underscores before upload

=====Add=====
var oldp = '';
while(p != oldp){
    oldp = p;
    p = p.replace(/\s+/, '_');
}
============

=== Complete =====
        onUploadChangeFile : function(e) {
            var f = e.form, p;

            p = '' + e.value.replace(/\\/g, '/');
            p = p.substring(p.lastIndexOf('/') + 1);
            p = p.substring(0, p.lastIndexOf('.'));
            var oldp = '';
            while(p != oldp){
                oldp = p;
                p = p.replace(/\s+/, '_');
            }
            f.name0.value = p;
        },
=============

Hope this helps someone!

Yes that is smart. The older versions had a similar replacement method it also replaced national characters like åäö with aao etc. We will think of a better method of configuring these replacements on uploads for future versions.
