I'm confused, it sounds like my third bullet point from above is what happened. You had 7/27 as the Logging End Date and a future date as the End Date? Then someone was able to log in on 7/27 and saw the
Notification When Logging Is Not Active message and weren't able to log? I think that's how it's supposed to work.
Edit: I think I get it! You put 7/27 becuase you wanted that to be the last day of logging and in the software that actually meant midnight on 7/27 which meant that on 7/27 people couldn't log. D'oh!
This obviously needs to be really clarified in the software so it's obvious what these dates mean exactly.
Sorry about that!!
