thank you for your post. The theme is not broken, the problem is that your website shows warnings and errors. You can see in the messages that it is only a warning, not an error. These messages are only for developers, and should only be hidden on public websites.
Please check your hosting panel and search for “PHP errors and warnings” settings, and turn it off. This will remove the warning.
The website and the theme is working without any problem, only the warning is visible.
If you don’t have this setting in your hosting panel please send us an email ( info @ 7theme . net ), there is another solution to turn off the messages, but for this we need a login for the website.
