I ran into this too when clicking a notification link in Lagrange, then click the back button and getting the cached page, then clicking the same link again.

I am guessing that notifications are being deleted from the database once clicked. Maybe serve up a special page in this event?

I think the page was current, one notification was from you, the other was from skyjake and that matched what I had in the notification email

Yeah they are being immediately deleted. I should actually change that so they are simply hidden once clicked and the actual deletion occurs a few days later. That way the links don't immediately break...

Also, I got missing info ("s/None") in a recent notification email, which suggests I forgot to fetch some data from the database after recent changes in the code. Will fix...

ok, i see, that is likely what I did. Maybe it would be better if the notifications stay until they are marked as clear or after an interval

I'm seeing notification-related exceptions in the server log, so there's definitely something broken there...

i can reproduce that by going back and forth on the dashboard page like @sirwilburthefirst described

I think notifications be a one-time thing is a reasonable pattern/expectation. If you don't want to take on the complexity of delayed deletion you could simply have an error page for when a notification can't be found in the database.

The exception has been fixed in v1.3, but the notifications still always get auto-cleared when opening notification links. I'll consider if it's worth the implementation time to keep them in the database for a while.

after using it a bit further i think the autoclear function is quite ok

I had 2 notifications from the email and the first one worked but the 2nd did not and afterwards both did not work
