dynamic css - fehlermeldung

langsam habe ich dynamic css installiert bekommen.
so einigermaßen funktionier das ersetzen der marker im css auch... nur leider habe ich jetzt immer diese fehlermeldung:

Warning: Invalid argument supplied for foreach() in typo3conf\ext\af_dynamiccss\class.tx_afdynamiccss.php on line 71

hat jemand ne idee ?

Hallo,

hast Du das Problem lösen können? Ich habe auch gerade die Ext installiert, und hatte das gleich Problem.
Und zwar habe ich in der Datei class.tx_afdynamiccss.php einfach einen check eingefügt, ob das array auch ein array ist.
Die veränderte Datei füge ich mal hier ein, vielleicht kann der/die ein oder andere das ja brauchen. Den Autor der ext habe ich auch benachrichtigt.

so long

Sascha
