Remove Hashbang

I run a store that’s hosted on GoDaddy and the URL has hashbang at the end. I found a script that’s supposed to fix it, but it didn’t work. I contacted Spreadshirt about it and they said their code isn’t compatible with GoDaddy. Can someone please tell me what GoDaddy does to their code and how to fix it? If there isn’t a way to fix it, then can someone at Spreadshirt find some way to make their code compatible with GoDaddy? There’s a WordPress plugin that embeds Spreadshirt stores in WordPress websites, but my store’s website was hand built using HTML, so that’s not an option.

Ahoy @tslewis
