Background - Before the software update and changes, I used to be able to post a PM to myself by creating a PM but leaving the "Add By Display Name" entry blank. Any PM I created this way was automatically generated with me as the sole person in the PM. I used it when drafting sticky posts and other things related to my forums for updating headers and such, allowing me to develop and save them until I had all the kinks worked out.
I attempted to do this again today for the first time since the software update and got the error message displayed in the attachment below. I'm guessing this capability is no longer functional and wondering, if I try to put my own display name in the box, will that make it work to create a new PM to myself???
I didn't want to attempt that yet as once the other error message showed up, it forced me to clear my cookies and get signed out/sign back in to get Stovebolt to work again.
The screenshot is attached.
