Good morning. It seems that now it works correctly.
One question: in the future, which is the process for installing theme updates?
Thanks.

Hello Rikard.
I’ve renamed old folder Enfold in the server to OLD-Enfold and then with my FTP software upload the unzipped enfold theme I bought to you.
But now in the WP desktop I have my Enfold Child that was there from the beginning and 2 themes: Enfold Versión: 5.1.1 and Enfold Versión: 5.2.1 (the last).
Must I delete Enfold Version 5.1.1?
Thanks for advanced.
JC.
