Problem with date and languages

Hello everybody!

So… After reading this post and making some research, I can’t make the date be displayed in spanish.

First, I must say I could make it work on a blank page I created using the information I got on the post, yet when trying to implement it on my website I cannot make it work…

It keeps displaying the date in English, could it be the bootstrap theme I’m currently using? I using Hyper theme bought on https://coderthemes.com/

Thanks!
