Hi Shelby !
The website is on line (no under construction) now.
You can go to https://www.pranichealing.es/calendari/?lang=es (this is the calendari section in the not default language: spanish) and go to other month (the next month for example: “Febrero”)
Then put the cursor on any event. See the url generated: the url adds a %2F.
If you click on it and go to the event details it open the default lang event detail, not the correct one (in this case the spanish event detail)
(notice that if you refresh the browser the problem is gone. If you want to see the issue again you have to do all the steps again)
Let me know if you understand the problem. If don′t please ask me again ??
Best regards
