When you install WordPress on your domain to create your website, then the default tagline of your website is displayed on the frontend as “Just another WordPress site”. It is a default tagline for any newly installed WordPress site.
Below is the step to remove the “Just another WordPress site” tagline.
Step 1) Login to your admin panel and navigate to the Settings => General.
Step 2) Now change the Tagline from “Just another WordPress site” to as you want and click on the Save Changes button.
After clicking on Save Changes button, the tagline will change. Go to the front-end website and see the changes.
