There is a JS error on your site, it could be conflicting the script.
I know you already cleared your caching, but please clear it again and Deactivate it for a while (also your browser cache, clear it again).
Then do a testing for a plugin conflict. You can do this by deactivating all third-party plugins, and seeing if the problem remains. If it's fixed, you'll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
If that does not work, you might need to restructure your section (equal-height), as what I am seeing now, you have 6 Rows, with multiple columns on that section and might complicate the script calculation.
Use the code (CSS or JS) provided here, I just tested it and it works smoothly.
