Unfortunately, there is still strange behavior in the backend. Several errors come up in the layout settings page, please see attached screenshot.
dirk-k
May I know which PHP version are you using?
PHP 8.0.21
dirk-k Are you using latest version of T3 plugin?
I tried to install the same at my end with PHP 8 but there is no warning like that.
You can hide these warning by settings error reporting under Global configuration to None.
Thanks for your reply. Yes, I'm using the latest T3 plugin. The error doesn't come up anymore now. I don't know what it was. Just logged out and in again and the issue was gone.
