How to Remove the "»" Character from WordPress Titles
1. Modify the Template File
In the template file, locate the function that calls the title, `wp_title()`, and modify it to `wp_title("")`.
2. Modify the Program File
Locate the file `wp-includes/general-template.php`. Open the file and find line 528, where you will see:
function wp_title($sep = '»', $display = true, $seplocation = '')
Delete the red string "»" in the code above.
(Note: It is generally not recommended to directly modify core WordPress files, as these changes may be overwritten during updates. Consider using a child theme or filters to achieve similar results.)
