[gelöst] [PS1.7.6.1] White Screens im Back Office

[Paul Sack]

Die Startseite des BO wird noch korrekt angezeigt, sämtliche Menüpunkte führen zu White Screens.
Der Effekt trat völlig überraschend auf - Module wurden nicht installiert, deinstalliert oder geupdated.

Erfolglos blieb bisher das Löschen des Smarty-Cache und ein  neu generieren der .htaccess.
Im Debug-Modus läuft das BO fehlerfrei - hat Jemand eine Idee ?

Dann ist es meist ein cache Fehler. Umbennen von /var/cache zu /var/cache_old lässt diesen neu generieren

[Paul Sack]

@JBW: ASTREIN !!! Nach Umbennen von /var/cache sind die White Screens verschwunden.
Danke für den Tip !
