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:

* 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

<h4>How to use the Flexible Frontend Login shortcode on your site</h4>
On the widget settings page choose the Flexible Frontend Login and adjust the settings to your site.
In a post or page place <code>[flexible-frontend-login]</code>
By default the shortcode uses the settings set on the admin options page
You can override those default values with the following parameters and options:
<ul>
<li><code>vertical=top, bottom</code></li>
<li><code>horizontal=left, right</code></li>
</ul>
So your shortcode might look like this:
<ul>
<li><code>[flexible-frontend-login vertical=bottom horizontal=left]</code></li>
</ul>
If you want to use the centered login form with darkened overlay in the background 
use <code>[flexible-frontend-login-modal]</code> without any parameters.
<h4>How to use the Flexible Frontend Login template tag on your site</h4>
In template files place:
<code><?php if ( function_exists('flexible_frontend_login') ) flexible_frontend_login( 'bottom', 'left' ); ?></code>
To change popups behavior you can use
<ul>
<li>“bottom” or “top”</li>
<li>“left” or “right”</li>
</ul>
For popup with overlay use:
<code><?php if ( function_exists('flexible_frontend_login_modal') ) flexible_frontend_login_modal(); ?></code>
