Thank you, David, that’s a BIG one!
I know what is the issue. First I was naming folder tinyforge (the same as theme name space or Text Domain), but later I noticed that when I download the zip from WP.org, it is packed in tiny-forge folder… most likely WP automatically repacks the files and saves under folder that is named same as theme slug in the WP.org repository.
So… I think it would be nice to have same naming all over the theme. I’ll see perhaps admins can change the slug here. Otherwise I will change name space to tiny-forge everywhere, to be consistent.
David, I realized that better method is not to change the folder name of parent theme (leave it tiny-forge), but open the style.css of a child theme and right at the top change the line:
Template: tinyforge
to
Template: tiny-forge
This way you’ll be safe in the future, because after talking to WP guys, I have to leave folder name as it is: tiny-forge
In the next version I will correct that line in child theme example.
Big thanks for reporting this issue!
