Yesod logInfo no output

I get nothing from $logInfoYesod.

I have a building site, and when I start yesod devel, I do not see the output from the log lines that I inserted into my application. I also tried to create an application (using cabal) and run from the command line, but still there is no way out.

I got the impression that in development mode all levels of the log are displayed.

What am I doing wrong?

UPDATE

I built a "fresh" application using the latest version of Yesod (downloading with cabal just now). I changed getHomeRin the Home.hsfollowing way:

getHomeR :: Handler Html
    getHomeR = do
        $(logInfo) "Greeting from getHomeR"
        (formWidget, formEnctype) <- generateFormPost sampleForm
        let submission = Nothing :: Maybe (FileInfo, Text)
            handlerName = "getHomeR" :: Text
        defaultLayout $ do
            aDomId <- newIdent
            setTitle "Welcome To Yesod!"
            $(widgetFile "homepage")

Then I ran cabal install && yesod devel. I connected to localhost:3000from my browser. I expected to see Greeting from getHomeRthe console output, but it was not there.
