Sorry for the long wait, but I thought I just get back with more info as it’s not 100% resolved. I can’t share the site URL here on this form.
I can tell you that after a wordpress update 2 months ago the plugin started working… more or less… Of the six logos we have in the standard wordpress footer gallery, only 4 of the 6 have an active custom link while the other 2 do not. The placement zone of the six logos does not matter. It is always the same 2that will not link off-site. We’re currently on WP 6.4.3, running PHP 8.1.26?with no log errors. Theme is Spacious Pro. If you email / PM me I can share the site.
