Upgrade to 3.5.1 and sidebar gone with infinity scroll

Hello there,

I have finally got to the point to update wordpress to 3.5.1.

However, when I returned to my homepage I saw that the left sidebar was gone. The page which is also showing following the link “Blogroll” was identical to the front page. The only thing I can do now is to make the front page static and to show the same content as the “Blogroll” page. However, the title of the page (and possibly other data as well) are different.

How can I set this up, so that the sidebar will also show again on the front page and not only on the blogroll page. I have not been able to find the checkbox to deactivate infinity scroll.

Thanks,
André
