dear all,

I have a few problems I'll try to detail:

1. the menu has disappeared from the top of the page. It was visible and perfectly ok, until it disappeared. I've tried changing the menus options, but nothing has changed. 

2. In section 3 (the one with the green background picture) I can't change the padding so I don't see the grey blocks on top and bottom, the same in the phone section.

3. The footer only allows to add social icons and copyright. How can I add columns? I see no widget or other option, please advise.

Thanks in advance
