[Solved] Deployed when changed all non-English character to be united English character and also created a sub-folder to put in server and ui files, but will need to modify when free :

  • renderUI() loading very slow
  • radioButton doesn't work
  • dashboardthemes only applied to sidebar but not whole website.
  • radarchart plots do not display in prettydoc knited html files.

I solved the problem by using navigate method, I used iframe instead of renderUI(includeHTML()) to speed up the page loading.

  • Only English version shows the radarchart
  • Only English version can linked to the title and sub-tittle by clicked the top content section
