@TheConfax, thanks for reporting this problem. Now I need to figure out how to reproduce the problem. If you have any ideas, please let me know.
I have a Chrome extension for switching my browser's language. When I set it to Italian the site redirects me from www.triggercmd.com to www.triggercmd.com/it, which is correct.
I'll do some research.
EDIT: I was able to see a problem when I used Edge and set Italian as my preferred language. I fixed it. Thank you @TheConfax!
