[qrmmr66]

dear sir
when using contro panel, I get the message that the certificate of starka.x10hosting.com is expired.

further, my zen cart website gives the error that cach folder is not writable while I checked it from FTP and file manager of cpanel, the permission is wel 777.
my other subdomein is absolutely down , as it gives the error thet due to this permission problem the site can not be on, whle the folder maharadata is wel writable.
see the error:
Mahara: Site unavailable
Your defined data root directory, /home/maxima/public_html/socvet.be/maharadata/, is not writable. This means that neither session data, user files nor anything else that needs to be uploaded can be saved on your server. Please make the directory if it does not exist, or give ownership of the directory to the web server user if it does.
$$$$$$$$$$$$$
the session directory is not writable : in : /home/maxima/public_html/socvet.be/cache

kind regards,
