    Aliases must be unique error after upgrading - content not showing

    I've upgraded a site from 4.0 to 4.5 and after the upgrade my main content area no longer shows the content properly. When i debug i get the following trace section:

    umbracoInit Done handling request

    umbracoPage   Element loaded: data

    umbracoPage Aliases must be unique, an element with alias 'data' has already been loaded!

    umbracoPage Pagedata loaded for Contacts (ID: 1070)

    The same error occurs for every page.

    My page types have no data fields with the alias data.

    I user masterpages and the area in question is a body area that consist of only one page field command:

    <umbraco:Item field="Text" runat="server"></umbraco:Item>

    If i enter some text in this placeholder other than this command it shows but the content of the Text data field does not show up.

    If i add a system field here (@writerName for instance) it will show up but no user defined fields show up. 

    The same occurs in every other template i user umbraco:item to display content.

    Other than that everything seems to work just fine.

    Is this some bug related to the updated XML scheme? I tried to re-add the field using the wizard but it output the same tag syntax as for 4.0.

    I was dealing with the same issue. Content wasn't being displayed on first page load. When I refreshed the page the content would load just fine. I deleted the /data/umbraco.config file and that seems to have fixed the problem. The new location for the umbraco.config in version 4.5.x is ~/App_Data/umbraco.config.

    I ended up deleting a bit more than that in the data directory. I deleted the _systemUmbracoIndexDontDelete as well as the umbraco.config file(i didn't try one by one). This was what fixed it for me in the end.

    Yeah, I ended up deleting everyting in the /data folder too, but for me deleting just the /data/umbraco.config fixed the error.
