Hi,

I have added a handlebar helper function in my code. Please find the code.

import registerUnbound from ‘discourse/helpers/register-unbound’;

registerUnbound(‘color-shade’, function() {  
return ‘this is sample helper class’  
});

I am getting an error due to invalid imports, and it is crashing the entire application and admin page also not working.

Please suggest me how can I remove this code / theme from my application in order to get rid of this error.

Thanks  
Kumar

Depending where you added the code, can you disable the theme or plugin using [safe mode](https://meta.discourse.org/t/53504?silent=true)?

`[YourSite]/safe-mode`
