You wakeup in the morning and your wordpress website is completely blank. Nothing shows up and you can not log into your wordpress admin. That is also blank. There are a number of ways to fix a wordpress website that shows up blank.

1. Try removing all of your plugins. Sometimes a plugin might act up and cause your entire website to go down. You have to physically remove all the plugins to fix a blank wordpress site.
2. Try deleting your themes. Then login in to yoursite.com/wp-admin.
3. Try overwriting all of your wordpress files except wp-config.
4. Still doesn’t fix your blank wordpress problem? Delete everything and start over. This may be the only solution.

As long as your mysql data is still there (where all the data and posts for your website are contained) then you should be able to un blank your website.

This happened to me this morning, I wokeup and for no reason at all my wordpress websites did not work. After reinstalling everything they no longer were blank. That was a huge pain in the neck but it worked.
