Braden that's an error while trying to render a different error.

Do you have another error message in the log file that might help find what caused the error in the first place?

The view error must be coming from here https://github.com/flarum/core/blob/v1.2.0/src/Foundation/ErrorHandling/ViewFormatter.php#L72 which should use this view file https://github.com/flarum/core/blob/v1.2.0/views/error/default.blade.php

Actually your last line is a different error for a different view file, error.not_found. So it looks like none of the error view files are loading.

Can you check that the files exist and are readable in vendor/flarum/core/views/error? If the files are correctly present, maybe an extension has overridden the entire Flarum view namespace and Flarum is looking in the wrong place. I'm not sure how to see if that's the case though.

clarkwinkelmann lol now you explained it well, it got into my head.
i checked vendor/flarum/core/views and i am missing error folder.

But why when i changed from 8.0 to php 8.1 it gives error
