Resolving “Error Loading Control” in the Work 365 Self-Service Portal

Audience: System Administrators, Support Teams

Overview

Users may encounter the error message “Error loading control” when accessing the Work 365 Self-Service Portal.
This issue typically occurs due to a temporary service interruption or synchronization delay between Power Pages and the Power Platform environment.

Restarting the Power Pages site from the Power Platform Admin Center generally resolves the issue.

Resolution Steps

Step 1: Open the Power Platform Admin Center

Navigate to https://admin.powerplatform.microsoft.com.
Sign in with an account that has administrator permissions for managing Power Pages sites.

Step 2: Locate the Power Pages Site

In the left-hand navigation panel, select Manage.
Choose Power Pages.
Click on your portal (e.g., SkyBlue PV Portal).

Step 3: Restart the Site

Open the Site actions dropdown menu.
Select Restart site.
Wait 2–5 minutes for the restart to complete, then refresh and test the portal.

? Note: Restarting the site clears temporary “control loading” errors but may cause brief downtime during the process.

Optional Quick Checks (If the Issue Persists)

Check: Browser Cache Action: Perform a hard refresh (Ctrl + Shift + R or Cmd + Shift + R) or test using a private/incognito browser window.
Check: Recent Deployments Action: If changes were made to web templates or table permissions, ensure all modifications are published and the site cache is cleared.
Check: Table Permissions Action: Verify that anonymous and authenticated user permissions are configured correctly for the affected tables.
Check: Environment Health Action: Review the Admin Center for service advisories, API throttling, or ongoing outages.

FAQs
