The message means exactly what it says. Unfortunatelly you have not posted the main message, so I can hardly tell when the problem occures.

BTW: I have deleted your duplicate post.

I get the following error message upon uploading plain .htm-files to my server. Why? And what do these error codes mean?
-------
Permission denied.
Error code: 3
Error message from server: Permission denied (*)
Request code: 3

Thanks in advance.
