By default, most themes link the logo to the homepage. 
This plugin removes that clickable link — so your logo stays visible but is no longer a hyperlink.
Features: 
* Removes the <code><a></code> tag around the logo automatically 
* Works with <code>the_custom_logo()</code> output 
* CSS and JavaScript fallbacks for full theme compatibility 
* No database modifications 
* Lightweight and fast 
* Works instantly upon activation
