I'm not able to save changes in "edit settings" tab in Portal for ArcGIS 10.6 (windows). I've applied the solution provided:https://support.esri.com/en/technical-article/000012316 without success. The text is the "organisation description" is short and simple. I've used the HTML editor to find problems with the text, but it appears similar to any text entered.
I'm baffled how else that can be approached.
Any help will be greatly appreciated,
