Forbidden
You don't have permission to access /index.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
why it happens that?
check CHMOD of index.php file thru FTP account / webhost panel
index.php should be 0644 or above ..
admin panel --> tools and maintenance -->
does the system warn of any incorrect CHMOD
nope it does not work and when i save those permissions at index it doesht save its just 0 0 0
Your host terminated your service, remember?
nope no one terminated....
If the CHMODs are set to 644, and you don't have a .htaccess file that could be causing a problem, then you'll need to ask your host.
