Hello together,
the mail text title of the Theme (bif white text with link to home page on the top left site) is in H2.
This is quite bad for the Search Engine Optimization of each site, that uses your theme. That means always, that the first H2 in the site is always the title of the whole website.
Rule should be:
H1: only one on site -> Title of the Blog-Post/Site
H2: Following H2 titles of each paragraphs, that are always defined by the user himself.
The first H2 on the site is now the WEbiste Title.
Same for H3 and so on.
