das Update auf 2.6 lief ohne Fehler durch, aber seither kommt bei manchen Artikeln folgende Fehlermeldung:
phpMyFAQ notice [8]: Undefined property: PMF_Helper_Category::$treeTab in Category.php on line 146

Ansonsten wird der Artikel aber korrekt angezeigt. Ich habe vorübergehend das error reporting von PHP abgeschalten, aber das ist natürlich keine Dauerlösung

Habt ihr eine Idee? Herzlichen Dank!
