I have all my alerts send emails that include a link to view the alert.
View Alert: ${N=Alerting;M=AlertDetailsUrl}
When I trigger on a node, the link works just fine no matter the age or condition.
When I trigger on an interface, the link works just fine while the alert is active.
If the link is clicked after the alert is no longer active, I get an 'unexpected website error'.

I'm just going to have to remove the link completely if it's only going to work to an active alerts.
Example: People checking alerts that happened overnight and getting a bunch of dead links.
Any ideas to help or has anybody had the same trouble?
Thanks~
