How to activate zoom function ?

Hi there,

this is the default viewport meta tag that theme inserts:

<meta name="viewport" content="width=device-width, initial-scale=1">

Which is different to what you have.
We provide a filter hook to change that:

https://docs.generatepress.com/article/generate_meta_viewport/

Did you use that in a custom function?

Hi David,
Since I had this error message first (<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0">), I added this code in functions.php of my child theme:
add_filter( 'generate_meta_viewport', function() {
return '<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=5" />';
} );
It didn't change anything...
I just deleted this code and I have this message again: "<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"> "
I don't understand where this can come from...

Ok, so thats correct the one that the theme adds.

BUT there is a second one in the head of your site, which looks like this:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0">

Thats not coming from the Theme.
Try disabling plugins to see if one of those is adding it.

To check if its there. Right Click > Inspect to open the Browser Developers tools, and CTRL + F to open the search field and search for: viewport

Your site shows there are 4 instances. You can ignore the 3rd and 4th ones as they are in an iFrame.

Ok, I found the 2 plugins possibly responsable of that... I will see that with them.
Thanks

Let us know how you get on

Following your advice, I found the plugin that was causing the problem...
It was PDF Embedder Premium, for which I had disabled zoom... I unchecked the relevant box. And the warning disappeared.
Thanks

Glad to hear that ! and thanks for lettings us know, as others may find this useful :)
