Problem after last update

Hi,

I have a couple of problems I just noticed after last update.

1. I had a social icons menu on the very top bar. Icons disappeared. Looks bad, deactivated the option for now.
2. I had a gallery of thumbnails in the footer, three columns layout. It was showing only on one column. I deleted the gallery for now.

I can wait/live without the first two and activate them again if needed, for evidence.

3. The third problem I notice is a margin at the top, just before the transparent menu. The margin stays there when scrolling the page, between the menu bar and the address bar. Please see this and this.

Will you please tell me what to do?

Thanks!
