Artikel erstellen

Hallo Leute,
ich habe mal wieder Mist gebaut (sprich irgend etwas verändert) und jetzt geht die Artikelanlage nicht mehr!!!! Hilfe bitte....
Hier hab ich schon mal die oxchkversion drüber geschickt:

Edition PE
Version 4.7.6
Revision 48acf618c43d333b81bb6636f7d13a3a75ec4638

Summary
OK 1476
Modified 28
Version mismatch 0
Unknown 212
Number of investigated files in total: 1716

This OXID eShop does not fit 100% PE_4.7.6_48acf618c43d333b81bb6636f7d13a3a75ec4638.

Hints
* OXID eShop has sophisticated possibility to extend it by modules without changing shipped files. It's not recommended and not needed to change shop files. See also our tutorials.
* Since OXID eShop 4.2.0 it's possible to use your own templates without changing shipped ones.

Ich habe eine ganze Zeit keine Artikel eingestellt, nur ein bischen am Design gebastelt (Ferienbild auf der Startseite usw.). Es gab ein paar Updates Seitens Oxid-Shop und ein paar Updates von D3, speziell der Importer.
Um den Fehler zudemonstrieren habe ich einen Artikel neu angelegt und einen Artikel kopiert, beide gehen in der Detailansichtnicht (Produktdetail):

Was habe ich falsch gemacht?
