When attempting to access a form, the screen becomes blank or frozen, and nothing loads. This issue affects only one specific user, and other users are able to access assessments without any issues.
The issue is caused by the uBlock Origin browser extension installed on the user’s machine. This extension may be blocking the main assessment page, preventing it from loading correctly.
Resolution
Resolve the issue by:
Opening the uBlock Origin extension settings.
Removing the blocked page entry from the My Filters list:
https://www.rio.organisationname.servelec.thirdparty.nhs.uk/rio/assessments2/assessmentholder.asp$subdocument
Once this entry is removed, the assessment forms should load as expected.
Recommendation for users
If other users experience the same issue, they should:
Check the uBlock Origin extension or turn it off.
Review their custom filters.
Temporarily disable the extension to confirm whether it is causing the issue.
We also recommend informing your local IT team, as uBlock Origin allows users to block pages and create custom filters. IT may wish to reset, configure, or lock down the extension so that important clinical system pages are not accidentally blocked.
This block may have been caused by the user clicking an option or pop‑up at some point, which automatically added a filter.
