Hey,
After downloading the Writter theme, I’m getting this error:
I’m not sure what this means or how to fix it properly.
Any help would be greatly appreciated.
Steve
I think this is a query that should be directed towards the theme author/seller rather than the Ghost forum per se…
But I think you just need to register a new integration/app in Ghost admin, then paste the new API key that’s generated into your theme settings. 
Check this page (Writter theme search API activation docs) for details:
