It's somewhat likely that the work Bryan was doing caused your browser to cache a redirect that should no longer be happening. 403 is a "forbidden" error which indeed dovetails with most security/permissions work on any web app. By clearing cache, cookies, etc., you should be giving your web browser a chance to reach out to the server and get the newest files since Bryan's work was completed. Could fix you right up.
For the record, your link takes me right to your store so I think you might be the only one experiencing the problem. Your knives at least will still get plenty of views.
