I can change the title of product pages in MK3 buy using the 'blog title' option in on the setting page. however, one the home page, the TITLE, i.e., the words that appear above the address line and on the browser tab, remain the same as ones i set a while ago. how can i change the title for the homepage to the new title used on the rest of the pages?

boomerstomexico.com/mexico-photos

old title, still on home page: Potographs of Mexico, Ajijic, And Chapala for retirement…

new title, on product and category pages: Mexico Pictures: Pictures of Mexico, Ajijic, and Jalisco

thanks for the help
