I did try several times but was impossible, but finally, instead of using the beaver builder page “add widget” option, I have I used a shortcode widget plugin, and used the option “add CSS” from the beaver builder page, and then added the shortcode. With that it has finally worked :)))
Thank you a LOT!
About the header, I mean that we want the header to be visible only in the home. But since in the setting options of the Event List, there is nothing about the header, it add it directly in the “eventos page”: http://www.punt6.org.mialias.net/eventos/
And I don’t know how to take it off.
