I'm trying to access Special:Chat from Extension:MediaWikiChat, but it says "You are not allowed to chat, try logging in first." even though I am already logged in. Example of the error: https://allthetropes.org/wiki/Special:Chat
Topic on Project:Support desk
According to https://allthetropes.org/wiki/Special:ListGroupRights only synops and chatmods have the “Chat” user right.
That is unusual. It says "Defaults to all registered users, except those in the 'blockedfromchat
' group"
