Hi @rakeshnagar ,
Ideally, if you navigate to "Service Portal → Service Portal Home", it should land on a new tab which should look like the following:
The blank Service Portal in a PDI is usually caused either by cached data in the browser/instance or by a bad widget/dependency or customization; start with basic checks and, if needed, verify the portal configuration and console errors.
Start with some basic checks:
-> Try opening the portal in an incognito/private window, or a different browser, and clear both the browser cache and the instance cache (System Diagnostics → Cache.do).
-> Make sure pop‑ups are allowed for your instance URL and that no ad‑blocker or browser extension is blocking the page content.
Check for errors:
-> Open the portal, then press F12 and look at the Console and Network tabs for any JavaScript errors or failed requests (for example “Failed to instantiate module sn.$sp” or missing dependencies).
-> If you see an error mentioning a specific dependency or widget, open that record (sp_dependency or the widget) and uncheck “Include on page load” or revert the recent customization, then test again.
Verify portal configuration:
-> Navigate to Service Portal > Portals and confirm that the portal you are trying to open exists, is active, and has a valid home page set.
-> If only this PDI is affected and you recently imported update sets or made heavy customizations, temporarily deactivate or roll back those changes.
If nothing helps, consider refreshing/resetting the PDI, which often fixes blank‑page issues caused by corrupted portal configuration.
