add new item and associate a new page

Hi every body ,
I create a new item [menuIresa] in DB and a new view "iresa.php" in /view folder.
The page is working perfectly and I already add pictures .
But when I add a new item [menuIresa2] and a new view iresa2.php , it doesn't work , an error message appears saying
"You selected '[menuIresa2]'.
This feature is not available on this version of ProjeQtOr.
Sorry…"
it's working with the first item and not with the second, what can be the problem ?
would you please tell me the reason and how can i fix it ,
thanks in advance .
