can't upload in ftp (net2ftp folders empty)

[mariaweb]

hi
there have been these problems lately...
this message comes up when im in the ftp and try to upload a file and files don't upload(i could do it some time ago but not now) :

Warning: ftp_put() [function.ftp-put]: STOR denied: quota exceeded: used 63444.61 of 10000.04 upload Mb in /var/www/ispcp/gui/tools/filemanager/includes/filesystem.inc.php on line 1283

there are also nothing in the net2ftp folders(i don't know if it's hidden or if it's suppose to be like this) , net2ftp_temp_w9ogi and net2ftp_temp_zr06

help would be appreciated
cheers,
Maria
