Logo not visible in header after moving WP from subfolder to root

Hi,

I moved the WP installation from https://mydomain.com/subfolder/ to https://mydomain.com/. Everything works fine, except for the logo not showing up in the header. When I scroll down, the logo becomes visible in the sticky header.

When I check the page source code, I see that in the section copied below a link to the logo image file is still showing to the upload directory in the subfolder in which the site was previously located.

<div class='container av-logo-container'><div class='inner-container'><span class='logo'><a href='https://mydomain.com/'><img height="100" width="300" src='https://mydomain.com/wp-content/uploads/[....]logo.png' alt='whatever' title='' />

<span class='subtext'><img src='https://mydomain.com/<strong>subfolder</strong>/wp-content/uploads/[...]logo.png' class='alternate' alt='' title='' /></span>

Please let me know how to change this, i.e. how to show the logo in the header. I tried changing the position of the logo in Enfold options, hoping it would rewrite the link, but it does not help.

Many thanks.
