Two different logos and favicons

by the way here is a nice generator for all icons – favicon, apple-touch icon, etc:

https://web-stuebchen.de/

can you please use for code the code element – it is better readable – and for you much more important it is copyable
it works either by click once on code button above – insert the code – click on (now it is /code-tag) this button after it
or insert the code – activate the whole block and click on code only once – than it will surrounds this lines.

your link is postid-4665 and it is a single post – see source code
For Logo change there is on enfold an option to do that by overwriting the other one but –

i tested that if on enfold options dialog a favicon is set ! it could not be overwritten by this method – so there is the code for the first rule is to set favicon for that single post the other for not to be that single post

the one is http://nowguide.no/downloads/ms_5564.png
what is the other favicon ?

you can see it here in action ( with is_page(330) – because it is in this case the page )
https://webers-testseite.de/elegant/flexbox-model/

all other pages got a different favicon.

so try this in your functions.php of your child-theme:

add_filter('avf_logo','av_change_logo_url');
function av_change_logo_url($url)
{
    if( is_single('4665') )
    {
        $url = "http://nowguide.no/wp-content/uploads/NorjobsideV2M-White.png";
    }
    return $url; 
}

add_action('wp_head', 'ava_add_iconnns');
function ava_add_iconnns() {
if( is_single(4665) ) {
?>
	<link rel="shortcut icon" type="image/x-icon" href="http://nowguide.no/wp-content/uploads/cropped-NorjobFaviconM-White.png">
<?php
}
if( !is_single(4665) ) {
?>
	<link rel="shortcut icon" type="image/x-icon" href="http://nowguide.no/wp-content/uploads/NG-Favicon.png">
<?php
}
}

and do not enter on enfold options on favicon something. Let the option free

2 weeks ago the question – ???
ps : just think of clearing cache to see the results – you are using Lightspeed Caching tool

The functions.php is a central part of every wordpress theme. And it is allmost in root directory of the theme.
On Enfold it is supported through functions-enfold.php. – The child-theme functions.php only ( its possible to overwrite things in parent-theme but) complements ( adds, expanding ) some functions.

so – are you using the enfold theme with a child-theme? That is important – and has a lot of advantages.
https://kriesi.at/documentation/enfold/using-a-child-theme/

the prebuild child-theme of enfold comes with an empty (only some comments are in it) functions.php .
This is always the case if you find here some snippets to obtain some customisations.

If you have installed a child-theme and activated it all benefits of the parent-theme are there but to bring some new code to it which does not go away on updates this functions.php is needed.
You can than edit it via ftp or via dashboard – appearance – editor
on the right side there are the (on start) two files in the child theme : style.css and functions.php
the mentioned code above comes to this place!
