Overwrite ScrollMagic issue on one website, but not on CodePen?

Warning: Please note

This thread was started before GSAP 3 was released. Some information, especially the syntax, may be out of date for GSAP 3. Please see the GSAP 3 migration guide and release notes for more information about how to update the code to GSAP 3's syntax.

In JSFiddle, what I have built works like a charm(timeline with boxes that fade in from left/right). This was copied from a previous website I Have created and it worked perfect there as well. However, for some reason on another website it simply won't work. The error thrown is the overwrite error and I simply can't understand why it won't work considering it's literally the same.

 

Done with ScrollMagic, GSAP, jQuery.

Hi and welcome to the GreenSock forums,

 

I noticed you have some errors about an element with class ".comprehensive" not being found.

 

Unfortunately, we do not support ScrollMagic (not our product) so you may want to check with their support.

It appears they have done a fantastic job of documenting this issue here: https://github.com/janpaepke/ScrollMagic/wiki/WARNING:-tween-was-overwritten-by-another

 

It just isn't feasible for us to try to dig through a live site that loads 20+ JavaScript files and do a deep forensic exploration with no way to test the code.

 

Since overwriting seems to be the root cause, you can debug when an overwrite happens using TweenLite.onOverwrite() and get some info on the tween that was overwritten and the tween that did the overwriting.

 

The demo below illustrates some of the features of onOverwrite. Perhaps finding the offending tweens will help you find the source of the error.
