Xpath Error after an upgrade on all nodes

Hi to all,



i have upgraded and then moved to another machine an umbraco 4 site. Now when i create a node i have always this error:



Page not found

No umbraco document matches the url ‘http://localhost/xxxxxxxxxxx/xxxxxxxx/ghgh.aspx

umbraco tried this to match it using this xpath query’/root/node/node [@urlName = “xxxxxxx”]/node [@urlName = “xxxxxxxxxxxxxx”]/node [@urlName = “xxxxxxx”]')



Besides when i’ve imported an xslt form 3 to 4 and then created a template and a document type

I’ve this error



Cannot find ContentPlaceHolder ‘MasterContentPlaceHolder’ in the master page ‘/masterpages/MasterTemplate.master’, verify content control’s ContentPlaceHolderID attribute in the content page.



But i don’t understnad beacuse in the master page i have the umbraco content place holder to substitute child node…



Is a mistery…
