    Unable To View Child Nodes

    I have a parent node, with about 8-10 children underneath. Recently, I have been unable to gain access to those pages in the Back Office.  I can browse to them in the front-end, and the arrow appears next to the parent folder indicating sub-pages exist. But when I click the arrow, it does not expand to show the children.  

    At first it looks to be loading, then stops and the arrow to expand disappears.  

    Before:

    After:

    Help!

    Fixed! I had removed a user (manually) who still had nodes attributed.

    Just needed to update the umbracoNode table and change the nodeUser

    Hi Justin,

    just wondering if you could help me out with the same error you've had. I'm got this on a few pages within a site we've built.

    for example I'm getting http://www.wuth.nhs.uk/umbraco/webservices/TreeDataService.ashx?rnd=0884dac504ce41c9bf24c793ef12b828&id=1709&treeType=content&contextMenu=true&isDialog=false&rnd2=30.5

    I've checked the umbracoNode table and changed the nodeUser from - '2' to a new users which I've created, however still getting the same error. Can you explain what you mean about the 'nodes attributed' - is this in another column in a different table?

    thanks in advance.

    Jamie
