Suddenly my portal sign in page is showing error as page not found.
no login or case related items are not visible.
when i checked on portal checker i got few of the errors, after resolving all these one error is left :
"A few entities with object names: applicationfile[4707], are used on your portal and does not have change notification metadata enabled. This can lead to cached data being displayed on the portal."
However all other object fields are visible in customize the solution -> entities section and I enabled changed notification metadata, but "applicationfile" is not found anywhere.
I tried using Metadata browser and found "applicationfile" but I am unable to edit that entity metadata.
Kindly, suggest some solutions.
