links not opening

I updated my site to joomla 2.5 sice then the other section of my site do not show. when i click each menu or link it gives the message:

The requested url was not found on the server
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

please how can i resolve this its really disrupting my flow.

maybe you have some rule u htaaccess file that is rewriting urls in bad way. Check if that appears if you turn off sef links.

how can i reverse it through the sef links
what code should i edit or type
please explain clearly.

send link, submit htaccess

This is the link
useast3.myserverhosts.com:2083/frontend/...&basedir=&codeedit=1

the login details are
Username: **********
the password :*********

Please also check the file/folder permissions
in the control panel

The link is:
useast3.myserverhosts.com:2083/frontend/...rishoc%2Fpublic_html


Please check, correct and test.
The home page is
www.afrisho.com
check all the links
Thanks.

That cpanel login does not work, newer send access data on public post use "Report To Moderator" instead.

By looking your site front it looks to me like your server dies not support url rewriting, or you have not removed . from htaacces. See what happens when you disable SEF.
