Microsoft Windows – `this.shouldEnforce is not a function` error thrown from `bat.bing.com/bat.js`

troubleshooting steps that may help:

  • Check for recent changes – If there were any updates to your website’s implementation of the script or related settings, reverting them may be worth testing.
  • Review browser settings – Ensure that browser security or extensions are not blocking or altering the script’s behavior.
  • Monitor error logs – If possible, provide more details on how the error is occurring (specific pages, user environments, or browser versions).
  • Check Console Errors – In the browser’s developer tools (F12 > Console), look for additional error messages that may provide more details.
  • Test Different Browsers – If the issue occurs only in certain browsers, there could be a compatibility issue.
  • Inspect Network Requests – In the developer tools Network tab, check if requests to bat.bing.com are failing or getting blocked.
  • Temporarily Disable Extensions – Some browser extensions or ad blockers may interfere with tracking scripts.
