i am using Kirby 220.127.116.11 with PHP 8.1 on Local and Production, since today i get the following error when changing text or a image or something else in the backend in the local environment:
is_a(): Passing null to parameter #2 ($class) of type string is deprecated
Can someone help me to get rid of this?
Thanks in advance.
Is there a stack trace for the error in your php error log or in dev tools console?
I don’t know how to do that sorry.
Do you get the same error with a fresh Starterkit?
Are you using any plugins that you haven’t also updated when switching to 18.104.22.168?
On a Mac, you open Chrome/Firefox developer tools with CMD+Option+I, Windows Ctrl+Shift+I
You can find the location of php error logs with the
As regards finding the php error logs, see Basic error hunting & prevention | Kirby CMS
thank you and sorry. it was a plugin.
