I faced a weird situation today, I was developing an app on R Shiny for some days and which was working on my laptop. Today I changed my PC (installed new windows) when I run my app it gave me this error:

This Font Awesome icon ('gears') does not exist:
* if providing a custom `html_dependency` these `name` checks can 
  be deactivated with `verify_fa = FALSE`
Error in widgetUserBox(title = "Alexander Pierce", subtitle = "Founder & CEO",  : 
  could not find function "widgetUserBox"

I check back it works well on my old laptop. I tried to install and follow Solution mentioned here, but nothing works. I also looked at this solution. Nothing works in my case. Kindly suggest help on the latest updated package from shiny, shinydashboard.

For reference I tried to run example code which is giving same error:

widgetUserBox(
                          title = "Alexander Pierce",
                          subtitle = "Founder & CEO",
                          type = NULL,
                          src = "https://adminlte.io/themes/AdminLTE/dist/img/user1-128x128.jpg",
                          color = "aqua-active",
                          closable = TRUE,
                          "Some text here!",
                          footer = "The footer here!"
                        ),

Here it was enough to change icon names according https://fontawesome.com/v5.15 like

> icon("dashboard")
This Font Awesome icon ('dashboard') does not exist:
* if providing a custom `html_dependency` these `name` checks can 
  be deactivated with `verify_fa = FALSE

will be

icon("tachometer-alt")

or gears to cogs

The solution for this problem is just to downgrade the new version of ShinydashboardPlus from 2.0.3 to 0.7.5.

Here is the code :

require (devtools) 
install_version("shinydashboardPlus", version="0.7.5",repos = "http://cran.us.r-project.org")
