hi there
by getting help from this link i put .htaccess file in to public_html folder by this content:
Options +FollowSymLinks
IndexIgnore */*
RewriteEngine on
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule . index.php
this codes say if I use a URL that does not match with files and folders in public_html folder, the application will redirect me to the index.php file, but actually it does not work
thanks in advanced
