Well, I logged onto my wordpress website – updated the theme – only that – no other changes and get the same behavior.
Header colors are a mess – all settings gone – background image blurred and the header customizer now displays some shortcodes to objects rather than an interactive menu.
For example, to change colors in the header text, I end up looking at this:
var(–nv-text-color)
instead of a menu.
I do not know what you have broken – but this is really not acceptable – will go and restore my backup now – as this version looks bad – and could only be fixed if I went and changed CSS manually.
