Unable to open NTA Web Pages due to error after dismissing the Notification Bar for NTA in the SolarWinds Platform 2025.1 Web Console

After upgrading to SolarWinds Platform 2025.1, the NTA pages will display a notification related to SQL Express. Once this notification is dismissed, the web page will produce an error message of "Unexpected character encountered while parsing value: &. Path '&#39,. line 1, position 2." or "Unexpected character encountered while parsing value: &. Path '', line 1, position 2."

Overview

You can dismiss the notification bar seen in NTA pages as seen below:

NTA Notification Bar

Once the banner is dismissed and the page is refreshed, a website error will appear on all NTA pages with the following message:

Unexpected character encountered while parsing value: &. Path '&#39,. line 1, position 2.

This issue only affects the user whose notification was dismissed before or after the upgrade. Users who haven't dismissed any notification bar will not be affected and will still have access to all NTA Flow pages.

Cause

The issue is caused by the changes related to HTML sanitation in SolarWinds Platform 2025.1.

Resolution

  2. Open Database Manager from the SolarWinds Platform of the Start menu.
  3. Select Add Orion server
  4. Expand the SQL server and SolarWinds Database in bold.
  5. Right-click the database
  6. Select New query. A query window appears on the right.
  7. Paste the below into the query window and select Execute query:

DELETE FROM WebUserSettings WHERE SettingName = 'TrafficAnalysis_DismissedNofications'

Once the settings are removed from the database, the users who had it saved can now access/view the NTA Summary pages.

To prevent the issue from reoccurring, do not dismiss the notification bar on any NTA page until a permanent fix is implemented.
