The issue stemmed from me deleting a webpage in my portal. I assume I must have accidentally deleted the entire website instead, as I immediately started having issues & the portal started behaving as though the website was gone (this delete action was done in the portal management app, as I was working on setting access/web roles).
As this was not an action I could Undo, I attempted to delete the portal and start fresh (to no avail), and as a second attempt, reset the portal, both times renaming with new URL (in my understanding, these 2 things achieves the same goal, it's just a different way to do the same thing, something Microsoft is very good a providing 🙂 ).
Unfortunately, today I still cannot edit the portal app (option greyed out), and when I enter the Portal Management app to edit, there is no website, no data, active or inactive, no pages or settings. 😞


I was hoping maybe the provision notice was just early, but that's not the case as both times I waited until I received the notice (via email as shown below), and tried again this morning, as mentioned above there's no change.

I think I will have to create a ticket at this point...I was hoping there was maybe just a CDS entity that was missing that need to be 're-added'....but this is looking like there won't be a simple solution.
I'd even be willing to create a new environment to start fresh, but I'm afraid that won't fix the problem, but instead create more.
Either way, thank you for the suggestions - I'm always appreciative of help, no matter the outcome!
