lib/functions.lib.php:178 ?

was meinst du damit?

Die Fehlermeldung sagt aus, dass
das Script in der Datei lib/sessions.lib.php in 4 Zeilen bestimmte Funktionen nicht ausführen kann, weil
in lib/functions.lib.php:178 (also Zeile 178) die Ausgabe schon gestartet wurde.

Daher hilft uns die sessions.lib.php nicht weiter, sondern nur die betreffende Zeile in der functions.lib.php (am besten auch 2-3 vorher und nachher)
