Thanks for your reply! Are you using the 1.2.0 or 1.2.1 version? I am asking you it because when I was using the 1.2.0 version it didn’t have the bug(the website is not fitting on my screen), I am not using any plugin or widget at the moment.
I am using 1.2.1(latest version) for theme demo. In version 1.2.1 I fixed bug with No-sidebar, Full-Width templates and didn’t change anything in the CSS. Didn’t add or remove or even edit a single line. If it was working earlier it should be working now as well.
Could you send a screenshot or something so I can get an idea what is going on?
