Hi @MichelyWeb ,
Welcome to the forum!
Are you using Cloudflare? If yes, please disable the “Rocket Loader” (thanks so much for the hint @krugerfamily).
If you have another provider that also offers similar options, try disabling them one by one. The same applies to installed plugins. If that doesn’t help at all, please send temporary login credentials and a link to this thread to help@bricksbuilder.io using the email address you used during your purchase (so we can verify you as a customer).
Best regards
