Error message when deploying app to Shinyapps.io

When deploying my app (shinyapps::deployApp('path/to/your/app'), I get the following error message:

error: Parsing manifest
################################## Begin Log ################################## 
################################### End Log ################################### 
Error: Unhandled Exception: Child Task 30191454 failed: Error parsing manifest: Unsupported locale: it_NA.UTF-8

It looks like it's got to do with encoding, as I am from Italy. However I didn't use any strange characters.

I tried "Save with encoding">UTF-8. I tried deploying it but I got the same error message.

It works fine when hosted locally.

ui.R

shinyUI(fluidPage(
  titlePanel("Probability Calculator"),

  sidebarLayout(
    sidebarPanel(
      helpText("Calculate posterior probability of an outcome"),


      numericInput("nofs", 
                   label = "Number of successes",
                   value=1),

      numericInput("notr", 
                   label = "Number of trials",
                   value=1),

      sliderInput("range", 
                  label = "Confidence Interval",
                  min = 0, max = 1, value = c(0, 1))


    ),

    mainPanel(
      textOutput("Calculator")
    )
  )
))

server.R

shinyServer(function(input, output) {
  output$Calculator <- renderText({
  x=1:10000000 
  denominator<-dbinom(input$nofs, size=input$notr, prob=(x/10000000))
  sommadenominator=sum(denominator)
  h1=(input$range[1]*10000000):(input$range[2]*10000000) 
  numerator<-dbinom(input$nofs, size=input$notr, prob=(h1/10000000)) 

  sommanumerator=sum(numerator)

  sommanumerator/sommadenominator
  })
})

This issue was solved thanks to Andy Kipp on Google Groups by fixing the shinyapps package. I had to redownload it and redeploy the app. Specifically: Please update your shinyapps package by doing:

devtools::install_github('rstudio/shinyapps')

Then try this:

options(shinyapps.locale.cache=FALSE)
shinyapps:::systemLocale()

And then try deployApp(), after making sure you've load the shinyapps library that you've just installed library(shinyapps)

I was getting the same error. First I tried updating the shiny apps package using Davide's answer but still received the error. I ended up deleted the Icon file that was auto-generated in my directory and then I was able to publish. I did it as a last resort though, since I'm not sure what the Icon file does and couldn't find any references about it.
