* Manlleus opted in to the beta feature and then opted-out again the next day: https://ca.wikipedia.org/w/index.php?title=Usuari_Discussi%C3%B3:Manlleus&redirect=no&action=edit&redlink=1
* Something didn't work right (details are unclear, I've asked for more).
* I found the situation as:
** a redlink at the usertalkpage, with the history in image 1 (below)
** A message at [[https://ca.wikipedia.org/w/index.php?title=Tema:St8tf44wbdcijhig&topic_showPostId=sujr1whls1g7cngg#flow-post-sujr1whls1g7cngg |this topic]] mentioning the problem
** So, I tried to move the archived Flow board back to that usertalkpage location, with the page-move tool.
*** It said it was successful, but when I opened the usertalkpage it had this message (image 2 (below)):
```Invalid value was provided for loading Flow content.
Return to Portada.
