For a while now I have had the problem where I try to login to WordPress and I just see the “white Screen of death”.
This is basically just a blank white screen, there is no html or error message. The website works fine, it was just when trying to access the admin pages.
The issue was some blank space at the end of the functions.php file. In order to fix, I used ftp to download the functions.php from my theme folder, then removed the extra spaces and lines and then re uploaded, and hey presto, its back to normal !
