That's a pretty general response. When you try this, I understand the Sqlite error still shows up. The only thing I can suggest is to delete the cache.db, though I'm told this does not fully solve the issue. If the OP didn't solve it, I'm not sure what will exactly besides what I mentioned, perhaps other members who have contributed may have an idea.
That's still a pretty general comment though...so...sorry if I'm not too helpful.
