Hello Leon,
Thank you again for your patience. The front-end editor on your website should now be working. The issue was caused by the Content Security Policy blocking inline JavaScript.
I’ve temporarily disabled the HTTP Headers plugin, as it was blocking these inline scripts due to cross-origin restrictions. If you’d like, you can re-enable it at any time. To make further edits, you’ll just need to disable it temporarily, and then re-enable it once you’re done.
To manage this setting, go to: System -> Plugins -> HTTP Headers.
If there’s anything else I can assist you with, please let me know!
Best regards,
