Many of you who are playing with SharePoint might have seen this error message before (:) ..."Invalid Associated Content Type". while working on one my Sharepoint Projects , i came accross this error of Invalid Associated Content Type, i first verified the Content Type that was associated with the Page layout and found everything was fine except one. The mistake i was doing was, not adding the following to within the Page Layout Content Type As soon i add the Content Type in , proper content Type's name apppears in place of (Invalid Associated Content Type).
