I'm not sure how but a client of mine's WordPress website is completely blank including the site/wp-admin pages. I'm not exactly sure when this happened, they notified me yesterday.
At first, I thought perhaps someone changed a setting in the database but I checked and everything appears to be as it should. To my knowledge, they haven't upgraded to the last release so I'm at a lost as to what's happen.
Anyone have a suggestion as to what I should check?
