Well, actually, I think so. After reading your post I gave another look to the theme file, which had GSAP 3.6.1 and ScrollTrigger 3.8.0 a couple thousand lines below (this one was actually the culprit of the errors, and I didn't see it before). Changed the code from both with the versions 3.11.3, queued the ScrollSmoother 3.11.3, and so far console is clear of errors, with a smooth scroll. Now, like @Yannis Yannakopoulos said above, I will run into problems with a theme update, but for now it seems to be all good. Thank you all for the help ?

True, that is exactly what happened. Thats where the new errors came from. I did not think of that. Will do it, the only problem is the time it will take them. They probably won't do it right away. I saw on a different post the user "ZachSaucier" saying he could provide old versions of the scripts. Was hoping someone from GSAP was kind enought to provide them as a short term solution for me ?

Hello, So, I'm using WordPress with a purchased theme, and they do use GSAP 3.6.1. When I try to import ScrollSmoother, it throws an error: Uncaught TypeError: Cannot read properties of undefined (reading '_getVelocityProp') Which, from my research, means version mismatch. I tried editing the theme files to remove the old GSAP version and put the most recent one, but other errors appear, making it really hard to make it work (Also, by removing the old GSAP code from the theme, the ScrollSmoother did work, hence I know is a version mismatch problem). As shown in the print, the ScrollSmoother is not using GSAP from the CDN, is using the theme file "plugins.js". Is there any way you guys know of where I can keep the theme files untouched and "force" the ScrollSmoother to function with the newest version of GSAP (let the theme use their own, and I import the most recent one)? If thats not possible, is there anywhere I can get the "ShockinglyGreen" suit of scripts on version 3.6.1 (I only found GSAP 2 Archive for download) so that I can work on this project without further problems from the theme? Thanks in advance
