Site Title Not Updating

The Site title (in the top of the browser) is still displaying "Simplicity > Page"

in the backend it shows my site title properly as well as in wordpress > admin > settings > general

in what php file is the title so i can manually change it.

Hi,

Did you disabled the usage of the GavernWP SEO settings on the SEO tab in the theme back-end?

If not, then theme gets the title tag based on the SEO settings in the theme, not in WordPress.
