404 Error – after 2.6.5 update

Updated to 2.6.5 2 days ago, now notice Locator not working. No map ever shows – just gets 404 on attempt. Any way to roll back to previous version? Also, I see this notice about this update:
BUG: the location search may have failed after settings update

If there is a bug with 2.6.5, how do I get around this? Is another update coming to fix this? Thanks.
