Wordpress Index.php not loading
may be the premits of htaccess disallow it from working, that will result not found pages
if you uploaded the script though root access
try this command
chown -hR user:user folder_path;chmod -R 644 folder_path/*.phpreplace user by your user name, replace folder path by the full path of wordpress
Edit:
The problem is your theme not include index.php
try to explore your theme directory, and check if there is index.php file, or switch to another theme
if the file is exists, Try to change file permissions use the command that i provided above again, i've edited it
