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.
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.
"We've boosted the Anti-Mass Spectrometer to 105 percent. Bit of a gamble, but we need the extra resolution."
