Hi, for a few days, I've been having problems on talk pages using Flow (including my own of course) on frwikisource, wikidata, commons...
one of the error message was " Erreur d’accès au serveur Parsoid/RESTBase (HTTP 400) "
I'll try to add new kind of error message when they occur, but the problem happens randomly, while editing previous messages as well as when answering... had it twice today, but did not have the reflex to screen capture it at the time...
