There seems to be some misunderstanding in your response. Unfortunately, your answer above did not address my issues and looks like you may have not understood the question. Kindly re-read my questions again.
I am already using Yoast the plugin and am aware of how to use it. I already addressed the htaccess portion prior to your response. I was able to generate an htaccess file on my own which hopefully is the correct one and wanted to double check with support. My question was whether the theme had its own htaccess to which you did not respond to (I did not need the standard one from Wordpress as I already have that). I was able to generate a new htaccess and wanted some direction if it was the correct one. It does not appear that you are able to answer that question?
I still need answers to my original questions which have not been responded to. You answered about how to add title, categories etc but that was not my question.
Rather, my questions are:
1) My Appearance Editor is not showing up in the theme. How do we make it appear so I can edit?
Your response "Regarding the Appearance > Editor some hosting service providers indeed block the functionality to change the content of the files using PHP language which what that section does" is not accurate. The hosting company did not do anything with respect to blocking the appearance editor as it was working just fine with other themes and prior to my installation of the X theme.
2) Your h1 tag is pointing to the site title as opposed to the title of the blog post. How do I change that? I am adding the h1, h2 and other h tags in Yoast but the X theme is not specifying the h1 tag as the title of the blog post and it is not mapping the h2 tag as what is specified in the blog post.
In addition, your h2 tag of the theme is pointing to "The Blog" instead of to a h2 tag that I may specify in my blog content.
This is extremely important for SEO and your theme default to it's own h1 and h2 rather than allowing us to to point the h1 and h2 and other h tags to the content in our blog.
Given that the theme was advertised to be SEO friendly, I am surprised that this has not been addressed and should be fixed immediately for everyone.
Kindly advise regarding my question on the h1 and h2 tags. If you need more clarification, please read this article which should help you understand my concern more: https://neilpatel.com/blog/h1-tag/
In the article above, you will note that it is important to specify the h1 tag and his is normally the title of the blog post. When I did an SEO audit, the X theme does not do that. So, please advise how to fix that.
If you still don't understand the question and need more details, please let me know
