In error I've installed a php script during my root directory, where wordpress can be obtained. Next my permalinks happen to be transformed. Once I modified .htaccess file and permissions file by ftp, now my site website is almost OK.

Still, I can not log-in admin panel. After I supply admin user title and password, the url I'm rerouted to is http://investorsbd.com/index.php/wp-login.php (extra index.php has proven) and states nothing found for index php login.

How do i remove that extra index.php for log-during my wordpress admin user interface?

Modify your .htacess file with below code

#RewriteRule ^(.*)-c-(.*).html$ index.php?cPath=$2&%{QUERY_STRING}

else do this code

    # BEGIN WordPress
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /dwellingventures/dwelling/
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . http://investorsbd.com/index.php [L]
    </IfModule>

# END WordPress

Hope it will help you
