The menus you're talking about... are these part of the standard CMS, or something custom, a sortable gridfield, etc.?
yes they add a new page on the preschool classses under programs menu
but im inspecting the Page.php it has a custom menu's included i think
should i edit the database manually to detect which page have problem ? it should be SiteTree_Live Table ?
Is there any way to validate the text field as a text only field?
I mean user can add just text only.
you mean no numbers or anything?
