WebSphere Portal Bug: Portal Theme “Breaks” in IE Local Intranet Security Settings

We have raised a PMR with IBM (#72308,000,834).

Our users highlight that the website “break” in IE whenever they click on the “Edit” mode button. The team examined and identified that this only happened to websites that are classified under Local Intranet Security settings (see screenshot below). This bug affects most of our intranet users as IE auto classified intranet websites under Local Intranet Security.

Current workaround: We advise them to exclude the site from Intranet Security settings or use alternative browsers like Chrome while we trying to get IBM to fix it.

In the example below, we will illustrate how to replicate the issue in your local environment using IE 11 and WebSphere Portal CF 9.

How to replicate:

  • Ensure that you have the following:
    • WebSphere Portal CF 9 and above (though we suspect this issue starts from the problematic WebSphere Portal CF 8 after they fixed the Site Manager bug)
    • IE 10 and above
  • Go to “Internet options” in your IE settings.
  • Go to “Security” and click on the “Sites” button.
  • Click on “Advanced” button.
  • Key in the website hostname that you wish to include in Local Intranet Security and click on the “Add” button.
  • Click “OK” button to close the “Local intranet” dialog.
  • Click “OK” button to close the “Internet Options” dialog.
  • Login to your website and toggle the “Edit” mode button.
  • *Poof!* The theme breaks!
