I managed to install the child theme, but I cannot follow the instructions provided. I do not see the child theme’s folder. I think you need FTP access or something. I do not have the tech skills for this.
I’m wondering why the heck would Themeco hard code H1 into the entire theme. That is completely ridiculous from a site structure perspective. I understand if it was hard-coded by a designer I used previously, but the impression I get is this is part of the theme - that would mean I have the same H1 header title on all my pages.
It seems that the issue is coming from the Site Title in the Settings area. If the Site title is added - the H1 is hard-coded on the site. If it is left blank, the H1 is still there, but shows up blank.
