Bettina,
This should not happen as a result of the update. Did you make any changes to the theme or add custom CSS?
Please provide a URL to inspect if this happens again.
Thanks!
I did not make any changes in the custom CSS. Here is the URL of my blog with the BLDR-Theme Version 1.1.2: http://www.artports.com/newsblog/
And this is my test-blog with the latest BLDR-Theme version: http://webproofed.de/neu/
Thanks for your support.
put this code in your theme’s Custom CSS if it is available or go to Appearance > Editor > style.css to set 3 posts in single row
you can see style.css at right side under the Templates.
.tri-clear:nth-child(4), .tri-clear:nth-child(7), .tri-clear:nth-child(10), .tri-clear:nth-child(13), .tri-clear:nth-child(16), .tri-clear:nth-child(19), .tri-clear:nth-child(22), .tri-clear:nth-child(25) { clear: none;}
