Troubleshoot: CORS Errors When Sending Feedback to Userback

If you've stumbled upon a CORS error while trying to send Feedback to Userback, this article aims to help you understand what's going on and how to fix it.

What is a CORS Error?

CORS (Cross-Origin Resource Sharing) errors occur when your website tries to interact with Userback but gets stopped at the door because it's not recognized as safe. Think of it like a security guard who doesn't know you yet.

Here's an example console message:

Access to XMLHttpRequest at '' 
from origin '' has been blocked by CORS policy:
No 'Access-Control-Allow-Origin' header is present on the requested resource.

Why Is This Happening?

If you're scratching your head because you haven't faced this issue on other websites you've developed, or if it's a new problem, here are some possible reasons:

  • Recent Updates: Your website or hosting service might have been updated recently.

  • Tightened Security: Sometimes, security settings get more strict.

  • Content Security Policy (CSP): Changes in CSP could affect the loading of fonts or other resources from external sources like Userback.

How to Fix It

Don't worry; fixing this is usually straightforward. You'll need to add a special instruction, known as a CORS header, to your website's settings. This tells Userback that it's safe to accept Feedback from your site.

Here are your options to solve this:

  1. Allow Any Task:

    Add Access-Control-Allow-Headers: *
  2. Allow Specific Feedback:

    Add Access-Control-Allow-Headers:

You can usually do this through your hosting provider's settings. If you're not sure how they should be able to guide you.
