I am using PhpEd and Dreamweaver on the same projects, and have not experienced this problem. If your FTP server log shows that the uploads succeeded, then the problem is obviously not on a FTP level (PhpEd). The problem is more likely your browser cache or some other cache, e.g. a proxy server somewhere between you and the destination.
What I typically advise our clients when they have caching problems:
* Try force a browser refresh with CTRL+F5.
* Clear your browser's cache.
* Compare with another browser or a different computer.
* Try accessing your website via an alias. If
http://www.yourwebserver shows the old info, try using http://yourwebserver (without the www prefix). Your development server may be set up differently; create an alias (e.g. ServerAlias entry for the VirtualHost) will give you this option.
