How to customize h1 in general settings

You will probably need to start customising your theme’s header.php template file via a child theme. What theme are you using? Where did you download it from?

Thanks. The theme is Blue Taste ver 1.3 by Jabox, an old theme.

That theme has not been updated in almost 4 years, may not longer be supported by its developer or be compatible with current/future versions of WordPress. I would strongly recommend that you switch to a more recent theme asap.

Thanks Esmi. I knew theme is old. Before passing to a new theme, how could I manage that h1 meanwhile?
