Why am I getting an author error on my blog posts?

Hi Shopify experts,

I was wondering if anyone could help me with following issue.

On our website we are getting following error message on author.

I18N ERROR: MISSING INTERPOLATION VALUE “AUTOR” FOR “NAPSAL {{ AUTOR }}”

When I look into blog post the author is properly filled in as you can see in pic below.

We are getting this error on all blog posts. Any idea how to fix that?

Our blog.json if that is correct place to look is following:

Hi, I can see from your page source that the data is loading from Shopify’s server as is. So this is likely a liquid issue. If you look into your theme code, you should be able to find a file that contains the word ‘article’ and ends in ‘.liquid’.

You want to go through those files and find the text inside of a class that matches ‘Article__Author’.

Inside of that span, replace the offending code with ‘{{ aricle.author }}’. You may need to replace ‘article’ with whatever the variable for the article or blog post has been assigned.
