What’s happening?
Customers are experiencing an "Invalid Content Security Policy" error on webpages, leading to blank pages on specific Power Pages sites.
Reason:
This may arise due to recent migrations or configuration changes in the Content Security Policy (CSP) settings, which can affect the loading of resources on the site.
Resolution:
- Confirm this persists after the migration.
- Suggest restarting the portal and clearing the browser's cookies and cache.
- If the issue continues, check the CSP settings, specifically the script-src directive, to ensure it allows necessary sources.
- Recommend using the Devtool extension to debug the Power Pages site to identify the cause of the issue.
- Run a Site Checker on their website to address any configuration issues.
- If the error is specific to a particular page, review the page configuration and any plugins associated with the entity referenced in the page
