We have main SP list say X, within that we have other child SP list say A, B and C. When I view all available list in the SP site I can view all list here (http://server/sitename/_layouts/viewlists.aspx?Basetype=0)
When trying to add new item individually to child list the NewFormUsr.aspx page opens with popup message "You are only allowed to add new items from the [Main List Name] Screen".
Going back to main list DispFormUsr.aspx page I can see a form with all columns of the main list and at the bottom all child list with a link to add new items to them. However, when we try to add new item to child list from this page the NewFormUsr.aspx
for child list gives webpage cannot be found error. I'm not sure why this suddenly started to happen as it use to work before. Can someone advice if they had similar problem and how was it solved?
