Seems I can post again. Thanks Shaw-Tony if you are out there.
@rickatk -- I just noticed that any attempted "reply" to a posting on the SECOND page of a thread triggers the error-message. I just reply to a posting on the first page -- that is successful.
Is that the same for you?
It is still happening.
Sorry, unable to complete the action you requested.
Seems to have been fixed.
