Unable to delete items in ArcGIS Enterprise 11.1

[MariusVerdes]

Hello,

I have a problem while trying to delete some layers from a folder in ArcGIS Enterprise 11.1. When I try to delete the items all at once from the portal page I get the following error "Some items were not deleted because they are delete protected or have dependent items.". They are not delete protected because I checked each of them.

And when I try to delete the items individually from the items settings I get an error saying "Unable to delete".

Does anyone else faced this problem before?

Also, I found the following support tutorial but it wasn't helpful.

Thank you in advance.

What kind of item are you trying to delete?

For example, If you're trying to delete a feature layer (not hosted), you must delete the Map image layer for this service first in Portal to delete the feature layer item.

Hi,

I am trying to delete some Insights Pages and an Insights Workbook that we are not using anymore.

I have the same issue but with a hosted scene layer.  Hopefully there is a single solution for both of us.
