It took me forever to figure out exactly where the corrupted data was located. The table has only 10 rows, but the hostKey value in each of them looks like they're not kosher utf-8. This was causing A LOT of problems, the biggest being that I could export the db, but I couldn't import it elsewhere.
If someone at WordFence wants to take a look at the table, I can e-mail it.
Just curious, what's the purpose of the data in that table?
