OK - there were some checkboxes hidden for me.
With Chrome and Firefox you will see this...
You need to drag out the dialogue box to see the checkboxes...
I now have an error which is similar to pbianco...
"Mime type not valid (application/force-download), allowed Mimes are image/jpeg - image/png - image/gif - application/pdf - image/jpeg - application/msword : "
I don't get this error in the sandbox. It is only on my server.
So its probably a php/apache configuration - as my server is locked down tight for security. I have certain functions disabled like shell_exec.
Does anyone have any clues to which server/php functions the file upload uses? (I'm still trawling through the forum)
