I didn't know about animation text bug before updating to v2 of helix ultimate... anyway, in one of my sites the only way that Animated Texts work is enabling one kind of "Predefined Header". If there's one activated, the animated texts work. If there's no predefined header, the console shows a javascript error and no animation works for texts:
Uncaught TypeError: can't access property "top", $header.offset() is undefined
getHeaderOffset https://.../templates/shaper_helixultimate/js/main.js:101
handleStickiness https://.../templates/shaper_helixultimate/js/main.js:138
<anonymous> https://.../templates/shaper_helixultimate/js/main.js:155
But as my design didn't have that preheader, I solved this issue by activating any Predefined Header and then hiding it by Custom CSS code:
#sp-header {
display:none;
}
This way I managed to get my animated texts working without the Predefinded Header.
I hope this helps to someone.
