Changing your blog title on WordPress is a fairly simple process. To do so, first log into your WordPress admin area and click on the “Posts” menu item on the left-hand side.
Then click on the “Title” field in the Posts editor and enter the new title you wish to use for your blog. Click on the “Save” button to apply your changes.
When you publish a new post, WordPress will automatically change the title of all of your existing posts to reflect the new title you entered in the Title field. However, you can also manually change the titles of any post or page by clicking on the “Title” field and editing it as you would any other text document.
Finally, remember to save your changes before exiting the Posts editor. If you make any mistakes while editing your posts or pages, simply click on the “Undo” button to restore them to their original state.
