When accessing /wp-admin a blank screen appears. The fix that worked for me was the following:

1. Backup current web files and database

2. Download a copy of WordPress from wordpress.com

3. Upload and overwrite website files with blank copy downloaded above

wordpres-ftp

*NOTE – this will not overwrite your theme and settings

4. Refresh site and update database if required (prompted on screen)

5. Done!

I believe this issue was caused by an auto update of WordPress although not confirmed.
