This issue is happening from client PCs only. If I open the browser on server machine using RDP then it works. Here's what's happening.

  1. Edit page
  2. Add Content Editor or Script Editor
  3. Write code <script></script> or <script language="javascript">alert("hello world");</script>
  4. Press "Save" button on ribbon to save page
  5. "The page cannot be displayed" error is shown in browser. Tested in IE, Chrome and Firefox.

But when I do same operation on IE on SharePoint server itself then it works fine.

Is it due to some security/firewall/AD/browser policy?

  • Hi Frank, it is always advisable to create a .txt file or .html in any library and then reference the link to your content editor webpart. try writing <script>##your code##</script> and see if it works. Oct 26, 2017 at 12:04
  • If you reload the page after seeing this, does it load properly? Oct 26, 2017 at 13:43
  • Yes refreshing it works fine because those scripts tags are removed. Oct 27, 2017 at 6:07

Use your javascript code directly in Script Editor without <script></script>

This will solve your issue

  • Doesn't work. Script Editor treats it as text. Oct 26, 2017 at 11:58
  • This is wrong. You need the script tags. Oct 26, 2017 at 13:42
