We purchased ArcGIS Portal and Server version 11.0 for our organization around 2 years ago. Recently, our navigation bar disappeared, and we can't even log in. On the console, we can see this message:
[Deprecation] Listener added for a 'DOMNodeInserted' mutation event. Support for this event type has been removed, and this event will no longer be fired. See https://chromestatus.com/feature/5083947249172480 for more information.
Our engineers are extremely disappointed and frustrated with the local ESRI Bangladesh support team, who are saying we have to buy ArcGIS Enterprise again.
I'm confused about why they would even say that, as we spent a lot on the system and this basic functionality isn't even working. I looked to see if Esri had released any patches for ArcGIS Enterprise version 11.0, but I couldn't find any.
Any sort of help would be extremely appreciated.
