Question: I recently migrated the site from a subdomain back to the main domain using WP All-in-One Migration Tool. The migration was successful and I can see the wp-admin panel just fine and even view the site while logged in.

But... when logging out the visitors just see the white screen of death. I have tried every fix in the book on Google, any tips would be appreciated.

Thanks!

Answer: 
```
DELETE FROM `{PREFIX}post_meta` WHERE meta_key = 'kksr_fingerprint_default'

```

{PREFIX} is the string `$table_prefix` defined in wp-config.php; of course be careful in run SQL DELETE, create a table backup and (maybe) execute first a single line deletion to check the result

```
DELETE FROM `{PREFIX}post_meta` WHERE meta_key = 'kksr_fingerprint_default' LIMIT 1 

```
First, make sure you back up your database. :)

If you're wanting to run a SQL command directly - perhaps using phpMyAdmin - the query would be

`DELETE FROM wp_postmeta WHERE meta_key = 'kksr_fingerprint_default'`
