i’ve had the same error… BUT thats because i really thought i had the right real-path… turned out i didnt. the path that ws-ftp AND the Control Panel showed me wasnt the correct one.
this i found out when i hovered over the upload directory in the File Manager of my Control Panel.
an adress occurred in the statusbar (bottom) of my browser (IE6)… it showed me the actual real-path i now use… and it workes!
the only stupid thing is that WordPress doesnt notice the fact that my first path was wrong and simply stated the upload was a succes… when it wasnt!
greetz,
