I just upgraded Kirby to 3.8.0 and cannot login anymore because of this error message:
How can I debug/fix it?
Check the php error logs for more details.
Which plugins have you installed and are they all updated?
I don’t know why, but now it is working as desired. Maybe there was something in the browser cache…
Hello,
I use Kirby 3.8.1 - and got the same error message.
Panel login works again after updating all plugins to the newest version.
