If you are using either Windows Vista SP2 or Windows 7, there is a bug in Dreamweaver CS4 when selecting an upload folder. to work around this bug, select an upload folder that is one directory higher than the actual target.for example, to set the upload folder to:
../uploads
you will need to select a folder within the uploads directory:
../uploads/folder
If you are still having problems,
1) make sure there are no other behaviors on the page that will redirect to another page.
2) on the bindings panel, expand the WA Uploaded Files Global Status group and add the Debug Info Binding to the page.
3) Add the following code at line 1 to turn error reporting on:
<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>
you say:
what is the error? I will need to know the error message to be able to have an idea of the problem. do you have a link where I could see the problem in the browser?
