Hey @vdnmanuel,
thanks for the follow-up.
I double checked it and it’s definitely via the Passter plugin that the page is password protected. What makes you think I used something else?
Because Passster isn’t touching the header or footer of the protected page.
The favicon is added in the hook wp_head(), but Passster only filters the_content().
A typical site structure (simplified):
wp_head()
Includes all the scripts, styles and so on for your website.
the_content()
Includes all the content for a particular page/post.
wp_footer()
Also includes scripts that are loaded in the footer area of your website and maybe some additional markup (like closing HTML tags).
You can also verify that by checking our one-click demo here: https://app.instawp.io/launch?t=passster-demo&d=v1
If you set a favicon and visit a protected page, the favicon is still there.
It might be a problem in conjunction with another plugin? Maybe a more or less unsupported page builder (We only focus on Elementor and Gutenberg).
