There are some triggers i created last week, which dont open on click… I cant clone it too.
Maybe a selected status that no longer exists could be the problem.
Can you please take a look into your production log and search for “ERROR” to see if something related might pop up?
Beside that, it’s poberbly a javascript related issue which blocks you here, you might want to open your developer console of the browser and navigate to the console tab.
When clicking on any trigger, it should throw errors there.
Just a guess: You didn’t happen to delete objects that are referenced in Triggers?
P.S.: Your guess has come true. I deactivated an object that was used in this trigger… After activating the object and removing the need in the trigger everything runs as desired again.
Maybe you could show a popup with the hint “Needed object deactivated or deleted.”
