Webpage fails to load about shinyitemanalysis HOT 7 OPEN

Please provide more information:
Are you running ShinyItemAnalysis locally in your R session? If running locally, please provide your sessionInfo(). You should also be able to see the Error messages it gives you (in RStudio, this will be in the Background Jobs tab).

from shinyitemanalysis.

Also, there were some issues with the Matrix library lately, try to update that library.
Perhaps the error message it was giving you was related to that library?

from shinyitemanalysis.

Here is the output from Background Jobs in rstudio... I couldn't see any error messages (but I am very new to R).

Updating the Matrix package didn't help.

@Samiam789 Please try ShinyItemAnalysis::run_app(background = FALSE) to run the app directly in your console. Wait for, say, 5 minutes and look for any prompts, warnings, or errors in the console.

Another thing to try is to reinstall ShinyItemAnalysis with all dependencies using:

install.packages("ShinyItemAnalysis", dependencies = TRUE)

Have you tried running a simple shiny app? Maybe your machine is configured to handle HTTP or WebSocket requests in some restrictive way. Please try:

shiny::runExample("01_hello")

from shinyitemanalysis.

The simple app seemed to run ok (shiny::runExample("01_hello").

Installing the dependencies didn't make any difference.

Running it with the (background = FALSE) also didn't make any difference. After 10 min I couldn't see any warnings in the console.

The webpage opens. The loading animation starts about 10 sec after the webpage opens and then remains. I can navigate to the data tab and if I click the browse button I can navigate to and select a csv file on my hard disk. But if I press the upload button nothing happens.

Here is the console output after running the app with the (background = FALSE)...
