Hallo, ich versuche, eine Website nur für Mitglieder zu erstellen. Ich habe versucht, ein Skript mit Sitzungen usw. zu erstellen. Wenn ich jedoch auf die Anmeldeschaltfläche klicke, wird die folgende Fehlermeldung angezeigt:

Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0

Fatal error: Unknown: Failed opening required 'prepend.php' (include_path='.:/Applications/XAMPP/xamppfiles/lib/php') in Unknown on line 0

Ich bin mir nicht hundertprozentig sicher, was das alles bedeutet, also werde ich mein Skript veröffentlichen und würde mich freuen, wenn mir jemand ausführlich sagen könnte, wo ich falsch liege, damit ich für die Zukunft nachvollziehen und lernen kann, was ich falsch mache .

Vielen Dank im Voraus für jede Eingabe und Hilfe.
