Error "page not found" after installing php script in cpanel

hello… i am having problem to get the admin details page after installing the script in Cpanel. The installation is getting successfully installed but after the when i go to the site then “page not found” error is coming. The link to my page is: Will please any one help me out in that? Thank you.

The problem can be from a redirect in htaccess, or in the index of your php script.
It redirects the Root (index.php) to a “/ist” category in url.

will you exactly tell me that where and what i have to look for or change?

Sorry, not know where you must to look, because i not know your script, and probably you not know php.
For htaccess just look in the file with that name, and post that code.
