Hi Alexandre Carol,
Thank you for reaching out, and I am sorry for any inconvenience.
Everything seems to be working fine on our end. However, please try the following if before head not works:
Ensure that the code is placed correctly in the Before </body> section.

If the issue persists, you can download the free Phoca Site plugin. This plugin allows you to add custom code to the <head> section and Google Analytics (UA ID).
Let me know if you need any further assistance.
Best regards.
