I apolgogize to keep writing about this rejects in the forum but there are some things that I literally have no clue what they mean.
-
Site title must be there by default: https://envato.d.pr/exeRwl
-
Don’t hardcode the text transformation, use an external stylesheet for that: https://envato.d.pr/Zd9h0a
-
Remove this please: https://envato.d.pr/WDjhMy
Thank you.
3 - You have some file in your project /theme which need to be removed/deleted .ds_store which is hidden. On your PC/Mac enable Show hidden files, find that file and delete.
2 - ‘COMMENTS’ replace with ‘Comments’ and add CSS selector like
h2.title {
text-transform: uppercase;
}
1 - I am not sure 100% about this but probably is following (I will try to explain):
In all my themes I always have the default logo and that default logo is always set by default when you install the theme (of course, there is an option in Customizer to remove/set your own logo).
But when you don’t have this default logo (which was a case with my Volos theme - it is designed without logo), by default I show the site title and description and I have a option to hide this text in Customizer.
You can see from my “installation video” here - https://www.youtube.com/watch?v=aq0GDBJgJSo&feature=youtu.be&t=170 - by default (in top left corner, bellow the menu burger) I have a Site Title (Volos) and Site description there but after that I am hiding that because I don’t use that in my demo.
I think, that is what they are asking to change/fix.

I don’t have such file, I set the view to show hidden files and I don’t see this file this is why I don’t understand.

Thank you it makes sense.

I see what you mean but you have a sidebar there with the menu, I also have this and I do show the title if a logo is not added in the theme admin both in the vertical menu and horizontal menu but the reviwer is showing a single blog post, where exactly I am supposed to add the title, I am so confused about this 
I appreciate your replay it was very helpfull.
You’re experinced author. Why don’t understand these simple issues ?
Because this are new things to me and I am very insecure, for example I had a _my word in one of my functions name, it was called something like get_my_clients and the reviewer told me to remove the my which makes no sense this is one of the reason and many others why I am very insecure when it comes to the reviwer requests and I don’t want to mess it up, I woked 16 months on this theme, it is my first theme and I am in frenzy mode 
I apologize if I stress anybody here is not my intention.
