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.
