I don’t know whether you have solved the issue or not but the solution is so simple and it’s simply described here in the previous posts..
change:
$settings = ‘mods_’.get_current_theme();
to:
$settings = ‘theme_mods_’.get_current_theme();
But the main things to remember is that php language support single only ‘ not the sign written in the answer.
I think now you got the answer.
