Hi Omanineyko119,
thanks for using MH Magazine lite.
The <title> tag on your website is handled by WordPress itself through add_theme_support('title-tag')
in the file functions.php.
However, we highly recommend that you don’t delete the title tag for your website. It would be a very unusual thing to do and also not good for SEO.
You can change the title and tagline of your website in your WordPress dashboard under Settings => General.
In addition you could make use of SEO plugins to alter the title tag on your website based on your needs and requirements for further optimization.
