Splited from T280972. See this backtrace:
Original message : Also, the translation on wiki pages cannot be edited. By clicking on "Save changes", an error appears. Try on one page. @Tgr , you may be interested in the result of the error Thank you in advance.
It should be solved on LinguaLibre, I edited and saved the page Translations:Help:Main/14/fr without issue (null edit so it does not appear).
@Tgr : I will publish the derived version from your change, this specific issue is the following diff:
diff --git a/extension.json b/extension.json index 0c42470..3d8c8f1 100644 --- a/extension.json +++ b/extension.json @@ -37,2 +37,3 @@ "MediaWiki\\Extensions\\OAuthAuthentication\\AuthManagerSessionStore": "store/AuthManagerSessionStore.php", + "MediaWiki\\Extensions\\OAuthAuthentication\\AuthBlacklist": "auth/AuthBlacklist.php", "MediaWiki\\Extensions\\OAuthAuthentication\\OAuthAuthenticationAccountRequest": "auth/OAuthAuthenticationAccountRequest.php",
I'd recommend using WSOAuth instead. OAuthAuthentication will have more features when (if) it's finished, but using a WIP patchset that was written years ago is invitation for trouble.
