I’m very sorry I bothered you with this question… It seems I forgot to update my functions.php
I had some custom code added in the old version, and did not expect it to have changed with the new version. Silly me! 😉
I just saw the extra lines for the pop-up:
'enable_popup' => ( basel_get_opt( 'promo_popup' ) ) ? 'yes' : 'no',
'popup_delay' => ( basel_get_opt( 'promo_timeout' ) ) ? (int) basel_get_opt( 'promo_timeout' ) : 1000,
);
