I am using nopC 4.10. I have a strange issue where I have the pavilion theme. A quick view at the page source reveals an h1 tag at div.side-2 > div.page-title > h1. And then again at div.page > div.page-title > h1. I think "side-2" is the side menu. Any suggestions?
this is specific for Pavilion theme - the designer of the theme wanted to have page titles in the side column, but only on catalog pages. As the page title source code defaults to a single markup position for the entire site, we used a "duplicate" to achieve the desired layout.
Regarding SEO, this is no problem as one of the titles (on pages where there are duplicates) is always hidden by CSS, and thus is ignored by search engines. So from SEO point of view there is only one page title.
