How can I resore ghosting of a page back if I accidentally unghosted it?
Will its deleting and recreating restore ghosting and remove copy of changed page from database?
Update:
Searched for quite a time om the internet and in SPD 2010 for "Reset to Site Definition" option.
It is not in the editing (or editor) of a page ASPX (what could have been expected where I've done changes) but on ribbon of settings page of a view page in SPD (Sharepoint Designer) 2010, under Page tab, immediately upon entering by clicking the entry in the list of "Site Pages".
