 * No, my site is only used to host WordPress. I have not made any administrative
   changes/updates to the underlying site in months, maybe years.

 * The MySQL server on my site says it has been running continuously for 48 days–
   so it doesn’t seem like the problem that started after 8/31 could be from a change
   to the MySQL server on my site.
