Tags and triggers are no longer displayed

I have the same issue. When reloading the page, I can see the correct content for a very short time, so it is there, just not displayed.

Console shows this error:

index.php?module=Proxy&action=getCoreJs&cb=37e17f08aed1fad5bb53fd683ea0ef26:41

(“Variables” page works, but shows the same error in console.)

From the Dashboard page I can open the page to create a new trigger. But if I try to save a new trigger, it doesnt work. Instead thees is an error (on ppage):

× SQLSTATE[42S22]: Column not found: 1054 Unknown column 'description' in 'field list'

this error also pops up in console (in addition to above error):

Uncaught (in promise) Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'description' in 'field list'
