Hi there!

Sorry for your experience.

Would you please give me your admin access to check the issue for you?

In the meantime, you may try the following steps:

1. Disable ModSecurity on your hosting server.
2. Ensure the correct file permissions are set for the template folder.

These actions should help resolve the issue you’re facing.

You can check this guide too: https://www.joomshaper.com/documentation/helix-framework/troubleshooting-faq#i-cannot-save-template-settings

Best regards,

please find access data for backend

Thanks.

Did you check the steps I mentioned above, please? That's important! Please let me know...
