I have installed shiny and shiny-server on an ubuntu server. I did a similar install on a dev server which is working. R sessions when they open up load some packages. The app runs fine locally but I'm getting messages that it can't find the packages when running on shiny-server.
The error on the app
During startup - Warning messages:
1: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called ‘shiny’
2: package ‘shiny’ in options("defaultPackages") was not found
3: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called ‘data.table’
4: package ‘data.table’ in options("defaultPackages") was not found
5: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called ‘optiRum’
6: package ‘optiRum’ in options("defaultPackages") was not found
Error in eval(expr, envir, enclos) :

Shiny is installed and is available in the Library of the
user you're running this application as.

In Rprofile.site I have
# ## Example of Rprofile.site
local({
# # add MASS to the default packages, set a CRAN mirror
old <- getOption("defaultPackages"); r <- getOption("repos")
# r["CRAN"] <- "http://my.local.cran"
options(defaultPackages = c(old, "shiny","data.table","optiRum"), repos = r)
})
.First <- function() {
cat("\n Welcome to R!\n\n")
# setwd("/home/OPTIMUMCREDIT/R/Projects")
Sys.umask(mode="0002")
}
.libPaths(c("/home/R/WorkingPackages","/home/R/ApprovedPackages"))
In shiny-server config I have just the default config (so run as shiny and default port).

I tried adding a message to output the libPaths above library(shiny) in my code but unfortunately the same error message happens. I did some uninstalling and reinstalling as I'd a bit unusually installed shiny-server first then remembered I needed shiny but no joy. I've confirmed that shiny is installed in ApprovedPackages. The packages at load up, I added in the hopes of circumventing the problem or finding out more information.
UPDATE - running as shiny Ah - the plot thickens... logging in with the user shiny on console caused the same warnings the app was getting, and .libPaths() is not like everyone else's:

I'm a bit stumped and was hoping someone could point me in the right direction to solve the problem.
