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.
- Edit page
- Add Content Editor or Script Editor
- Write code
<script></script>
or<script language="javascript">alert("hello world");</script>
- Press "Save" button on ribbon to save page
- "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?
