Hello. Whenever I shrink down my website it starts accommodating accordingly when around 1400px and further down. If I keep doing it there is a point on which the main container and the right sidebar collapses to the left, leaving an ugly empty space to the right.

If I were to stretch the window even more, it gets fixed. it looks like there is a media query or responsive breaking point that is not set up properly.

Can you guys help me fixing this issue?

Edit: I realized the right sidebar is hiding below the main container for some reason. Please help.
