Kategorien umgekrempelt...Absturz

Hatte gestern ein schwereres Problem die ich alleine in die Schuhe schieben muss. Als ich sah das ich in einer Kategorie die Unterkategorien noch besser gestalten könnte passierte es: plötzlich kam eine Parse Error Seite...nichts ging mehr. Ich ging dann zur Datenbank und rufte die Fehlermeldungen auf, ich sah darin dass genau dieser Bereich der Kategorien entsprach wo die Fehlermeldung kam, löschte darin die Fehlermeldung. Danach kann ich wieder ins Backend gehen...Jetzt kommts: obwohl in den Kategorien die Artikel nicht mehr sind, sind sie aber auf der "Neue Artikel" Seite immer noch vorhanden? Wenn ich diese anklicke findet er diese natürlich nicht. Hänge jetzt mal die Logs von gestern an:

Meine Frage: Von mir aus kann man diese Artikel löschen, den ich habe die Kategorien neu gestaltet und will die Produkte neu aufsetzen. Wie sollte ich vorgehen?

 

Danke für die Antwort Harald.
Habe ich bereits gemacht, unter "Cache für Artikel- & Kategorienzuordnung neu erzeugen" kommt folgende Fehlermeldung:

 

Danke für die Antworten, bin jetzt gerade in der MySQL Datenbank....

edit: Habe dort nichts gefunden

edit: Setze jetzt den Vorschlag von HaraldT um, habe jetzt mit meinem Provider Kontakt aufgenommen...jetzt heissts abwarten....melde mich wieder

 

Mein Provider hat das ganze vom Vortag überspielen lassen. Jetzt funzt wieder alles.
