can't access www.livesite.com/admin I have just transferred my local server to a live site. I am able to log in as an administrator, but I am not able to access my administrator tools. The page directs me to a blank page. Initially I was able to change the site's theme, through the admin tools, but now I can't even do that. I am not sure what am I doing wrong, or if there is something that I have to change in the settings.php file etc?

Btw, the site update was using ftp only.
A blank page often indicates a PHP Error. Is there an error in the PHP error logs you can reference?

Also, when uploading via FTP, you want to be sure that you properly transferred your .htaccess file which, on some Operating Systems, will be hidden on your local filesystem.
