Activating WooCommerce plugin add numbers to url?

SOLVED
It was woocommerce, it has a setting “geolocalize users with cache support” which adds this parameter to every single url and link. I noticed that the hash appended was the same in every browser on my computer, so I realized it wasn’t a “session” hash, but an IP address hash.

Great to hear you found the solution for that already. I’m going to mark this thread as resolved as well. Have a great rest of your day!
