Everything all right, but today....

I can do ftp upload, I see the files, but:
I can't download them,
index.html is OK,
forum database mysql is OK.

In zymic control panel the top of the page is strange, with this error:

Warning: is_dir() [function.is-dir]: Stat failed for /www/99k.org/m/a/n/mandriva/htdocs/forum (errno=13 - Permission denied) in /var/wkscript/common.php on line 369

Is it a permissions problem?
