CSP Breaking Site

What This Means

This issue occurs when a Content Security Policy (CSP) blocks resources required for your site to function properly.

This may result in broken layouts, missing scripts, or non-functional features.


Common Symptoms

  • scripts not loading or executing
  • styles not applying correctly
  • images or fonts missing
  • features or integrations not working
  • errors appearing in the browser console

Why This Happens

CSP restricts which sources of content are allowed to load.

If the policy is too strict or incomplete:

  • required resources may be blocked
  • external services may not load
  • inline scripts or styles may be prevented

How to Fix It

Try the following steps:


1. Check Browser Console

  • open developer tools
  • look for CSP-related errors or warnings
  • identify which resources are being blocked

2. Identify Required Sources

  • determine which domains or resources are needed
  • review any third-party services (analytics, CDNs, integrations)

3. Adjust the Policy

  • update the CSP to allow required sources
  • avoid overly restrictive rules
  • apply changes incrementally

4. Test After Each Change

  • reload your site after updating the policy
  • verify that functionality is restored
  • continue refining as needed

5. Revert if Necessary

If issues persist:

  • remove or disable the CSP configuration
  • restore normal site behavior
  • reapply a simpler policy if needed

What to Expect After Fixing

After resolving the issue:

  • blocked resources should load correctly
  • site functionality should be restored
  • CSP can be refined gradually over time

How to Verify

  • reload your site and test all functionality
  • confirm that no critical resources are blocked
  • review console messages for remaining issues

When to Seek Help

If the issue persists:

  • document the blocked resources
  • include console error messages
  • provide details about your CSP configuration
  • contact support with this information

Key Principle

CSP should be applied carefully and refined over time.

Start simple, test thoroughly, and expand only as needed.
