Hi,
Thank you for all your help.
After several attempts, finally I can save and publish changes via Appearance->Customize.
I really don't know what options I moved, but after I disable some options, I'm still wasn't able to save changes. I deactivate plugins and it didn't work either. I activate the plugins again and suddenly I finally can save changes.
Hope the AIOS plugin can protect my site with the options I leave active.
Thank you again for all your support. Now I can continue enjoying the Soledad Theme.
Regards,
