Today, I fetched the content files via rsync from my clients remote server to work locally on new things. But now I get this error accessing the panel (directly after submitting the login form):
Argument 1 passed to Kirby\Toolkit\Str::before() must be of the type string, null given, called in /Users/macx/Projects/amazing-outcomes/ao-website/dist/kirby/src/Cms/Language.php on line 460
I don’t know how to identify the problem. Strange. Language.php only have 110 lines of code, not 460. How can I debug this issue?
