I created some time ago
a Github Pages site using TiddlyWiki, which i was updating without trouble (albeit infrequently) until today's update, which -for some reason i cannot fathom- does not show up at aforementioned URL, tho it does show up
in the Github repo for the site as having been published.
This is strange, because i've been doing this without problems up until now. Most recent post listed under "Recent" tab says 10th October 2020; that was indeed the last post until today, which i published via the same workflow as that prior post: from TiddlyDesktop to a local folder that i push via Atom to Github. This post of today is there in the repo, in the "Tiddlers" folder that was updated 1hr ago as of this writing; Github Pages is "Active", and its Activity Log shows this update of last hour at top of log... But click thru to "Deployment" and it is not there.
This being more of a Github/ Pages problem, i hope i'm not out of order posting it here... But if anyone can suggest a plausible theory of cause, i'd sure appreciate it, because i'm totally stumped for one at this point!
