I found the below information and think this might be my problem, but I am unable to activate the default 2014 theme. I am new to wordpress and unsure how to use ftp, can anyone please help?
– Your Theme may be causing the problem. This is especially likely if you are experiencing the white screen of death after you have just activated a new Theme. Log in to the WordPress Adminsitration Screens and activate the default WordPress Twenty Fourteen Theme. If you can’t access your Administration Screens, access your website via FTP and navigate to the /wp-content/themes/ folder. Rename the folder for the active Theme.
